Title: Add reverb and channel switch to a Marshall Jubilee
Post by: Marshall Arts on March 12, 2016, 07:43:50 PM
Most people will say, that this amp (a Marshall Jubilee 25/50) is perfect as it is, but I always missed a couple of things:

- A reverb (footswitchable, with LED)
- A footswitch for the channel with LED

So, I filled a 1590B with two relays, a 1776 Rub-A-Dub-Reverb and upcycled an old footswitch (had that with my first ENGL-Amp, more than 25 yrs ago ;-)). It works fantastic, not the most fancy thing I built, but probably the most useful. The footswitch requires no batteries and is connected with a standard TRS stereo 1/4" cable. With no footswitch attached, I can switch the reverb on/off with the little switch on the enclosure and I can change the channel as usual with the push/pull pot the amp came with.

I will add a slave power outlet in the rear of the amp, so it switches on automatically when I switch on the amp.

That's awesome man! I want a silver jubilee so bad. I'm a major Slash fanboi, lol. I wonder how good the reissues are?

I've heard nothing but good things about the 2555x. A pity they haven't reissued the combo 2554 with 25/50 Watts so far (I do living room to small jams, a 4x12" and a top are a bit too much for that). For a smaller budget, try this:

Sounds pretty spot on, at least on youtube.

Well... thanks. I was too lazy to draw it in EAGLE, sometimes FRITZING or DIY Layout Creator are just good enough ;-)

Finally, I found the time to put this in my amp. Master/slave AC switches the verb on and off with the amp.
