- Step by step installation of the Ultimate FX Loop, available from Granger Amplification. Always practice appropriate safety procedures when working with vacuum tube amps and electronic equipment, and ALWAYS wear eye protection!
So I just ordered a JCM800 style Amp Build kit and I'm also ordering this piece to go along with it. Wish me luck!
I'd love to learn more about electronics (repair, mods) in general. Can an FX loop be added without having to use a small circuit board like this one? I have two different amps that I'd like to have a loop on. An Orange tiny terror and also a Marshall MKII 50 watt combo amp... I think I could and would like to DIY it as a learning experience and it should be successful. Would love to hear your thoughts. Thanks, and thanks for the video!
Yes, you can add a passive loop - just send and return jacks wired between the preamp and phase inverter. Many examples are online, including layouts by Ceriatone. Look there at the British amp series layouts. Also search for info on the differences in passive vs. active effects loops.
@@Grangeramp Thank you. Checking into it...there's a lot of information. I found a few photos online of the Tiny Terroe with fx mods added. Some with just send/return jacks, and one that has level knobs for each! I would love that mod... Now how to do it... I sent the tech an email but no reply yet... Thanks again.
I have a Laney Cub 8, there are only a tone and master volume control. I'm planning to put an effects loop, I thought it was just putting something in between the pre-amp and the power amp
This, and most loops are installed between pre and power amp.
With the loop "always on," would there have to be a jumper patch cable used if just going to in the front of the amp?
No, the signal will pass through when the loop is enabled, if nothing is plugged into the send and return jacks. No jumper needed.
If I send you my schematic, can you show me where to break and insert the fxloop board?
I have a Ceriatone King Kong 100. It already has a passive effects loop, can this effects loop kit be installed on that amp too?
Yes, it should install fine. The jacks are spaced 1.5 inches apart, so if that's the passive loop's hole spacing in the chassis, it will be a straightforward install, with the addition of the one extra hole for the bypass switch. Alternately, you can forego the switch and wire the loop always on if you'd like.
Where can I purchase the fxloop board?
Would this product work in a 18w TMB Marshall clone? Looks to be a pretty simple install.
Yes, it will work in most tube amp designs that have at least 300VDC available for the supply, and an appropriate insert point between preamp and power amp.
does this loop is compatible with marshall lead 12 ?
will this work for a yamaha thr30ii
Do you have a video that could help me install the mojotone fx loop on a hammond m-3 organ?
No, I suggest contacting Mojotone for help with their loop.
Nice job. I have a SOVTEK ALL TUBE LEAD MIG100 without fxloop circuit and I need to know if it's possible to install a fxloop circuit board.
Thank you
Yes, installation should be fairly easy in that amp.
Granger Amplification thank you
is this tube amp only or would it work in a Fender Champion 20?
Tube amp only. Needs high voltage to power it.
I have a Marshall dsl 15c. I would like an fx loop installed. Is this possible to do for a dsl 15c? And could it be footswitchable?
Yes, I have specific instructions written for the DSL15C. It is not footswitchable - for that you'd need to install a powered DPDT relay (which I also sell in the Granger Amplification Custom Shop - 1 Relay Switch Board) and wire accordingly. Easy enough for any experienced amp tech.
Where on the back panel would you suggest locating the loop?
@@lukejohnson7558 there's one place it will fit and that's where the Marshall print is. There's a pre-cut slot for wire routing, that's where I mark the center bypass switch to go. Bend that tab up and widen the hole slightly, then drill 2 more for the jacks. It's all in the instructions.
Very nice, is it possible to mod a vox ac15?
Yes, I believe so, as long as there is enough chassis space for the board. Email me via website and I can provide dimensions.
Hi Granger, interesting video. What's switch between input and output used for? Is it useful to put a mix pot, in order to have gain control of the return?
That's the bypass switch. The level controls are mounted behind each jack, and accessible externally using a small, flat blade screwdriver.
Hi
Do you think someone who can solder a little and has the right instructions is quallified to do this for personal use?
And do you think this would work on a valvetronix modeling amp like a vox vt40+?
Thanks
Patrick It's one of the simplest of our kits to install, however you do need to know proper electronics safety when working with any amplifier. The instructions are step-by-step, and very detailed. I can't advise to that specific model amp, however. That amp is likely all solid-state, and would not have the proper supply voltage required.
Granger Amplification it does have a tube in the preamp, with a power switch which you can turn from 5 to 60watt and everything between and it uses amp simulators and inbuild effects.
what do you mean by the proper supply voltage?
and i'm not really planning to instal a fx loop in it now, but i just wondered.
i ám planning to do some pickup re wire mods for other configurations, but i bought a 35 euro guitar to practice it on in case i screw up, so i have no worries for that.
@@Patrick33194 7 years and still unanswered! I want to install this to my vt40x but not really shure if it'll work.
@@_segori srry bud, still havn't tried.
Pls lmk how it went if you're gonna do anything like this
I would like to add an effects loop to my bass breaker 45
it could be installed in a marshall 10cd?
No. The 10CD is solid state. It does not have a high voltage supply necessary to power the UFX board.
Do you have a schematic? I want to install one on my Burgera v5 amp
Detailed instructions and a basic schematic for insertion between preamp and power amp are included.
hey great video! i'm looking at doing this to my Vox AC15? thanks for the info
Thank you!
How much (ballpark) would this run for a fender twin rev? Kit installed?
Installed it runs around $150. Depends on how much drilling is required.
+Granger Amplification thank you for your prompt response! I will take my amp in for this.
Do you have a video on draining capacitors to begin doing this kind of work?
Both Granger and Mojotone make an effects loop, are they essentially the same quality?
Brian Cullen Sorry for the very late reply. (We stay busy!) Very similar to the Mojo and Metro loops. All very good quality. For safety procedures when working with tube amps, there are some very good sources online that explain this in detail. As every amp is different, we only provide basic advice for draining the power supply.
Would it be possible to install an FX loop on a hand wired vox AC15? And how much would it cost?
@@demolabstudio2062 Easy. Tree fiddy
Any idea if I can do this on a tone king imperial mk 2 head
It should function fine in that amp, you'd just have to figure out where to mount it.
@@Grangeramp I messaged a few amp guys in the UK. Apparently it can't be done as the way the amp is designed all the overdrive happens in the power stage, that dosent mean a whole lot to me tbh. Any ideas?
How do these compare to the metro zero loss effects loops?
Very similar. I've never examined one of the Metro loops, but believe they also use the LDN150 MOSFET as the active devices, as both use a node from the B+ supply to power the board. I use board-mounted trim pots located behind each jack to set levels. I believe theirs uses separate chassis mount pots.
It would be interesting also a video on how to mount the Variable Power Control - VPC1 Kit for those like me who do not understand electronics. The fact of not knowing where to put your hands and always having to resort to a technician for installation discourages me to buy the mods.
Dario Van Halen I understand your concern, however we can only provide limited tutorials/instructions, because as you know, there are literally 1000's of amp models, and what works for one will probably be different for another (especially when modifying a high voltage power supply), and would only add confusion. Modifying tube amps is generally not for the beginner electronics enthusiast. What I recommend is to start with low voltage effect pedals, and once the student's knowledge of electronics is sufficient, then advance to vacuum tube amps.
Where's the audio? Ok, now I hear a drill etc.
Some speaking dialogue would have been useful.
The "speaking" is in the written instructions for anyone who purchases the kit. :)
1:10 Omg, use a drillbit ffs.
You've never drilled into and cracked Plexiglas or acrylic I take it.
