I was wondering if it is possible to save the modulation, delay, manual, tap, etc. buttons to a midi controller where say 1-4 are the channels that are on the amp but 5-9 could turn the mod, manual, delay, and tap controls to add the effect to any of the other pre selected 1-4 channels? Thanks!

Oh HELL yeah!

Thanks! I just had to put a grill on the front so I could see those hot tubes sizzling inside the cab!!! Mmmmmmmmmm!

Here is the head cab I made for my combo chassis.

I wanted to add that I left a small gap below and above the chassis for any extra heat to escape. You can see it in the pic.

I checked them and they were about 1.4 Ohms each. I put them in and the amp biases right and sounds great! I have both sides set at about 72 ma. Thanks so much for your help! I can think I know what to do, but it sure helps when someone that really knows tells you what the outcome should be. LOL! Th...

I checked it. Set my meter on 200 Ohms and it read 10 Ohms. (After I removed the two in parallel). I'd guess at some point the original resistor was blown and they couldn't find the 1 Ohm resisters so they got as close as they could by paralleling 2 -10 Ohm's to make a 5 on each side. I have the rig...

R48-49 are the 1ohm resistors used for biasing the amp. This method is based on ohm's law of " one mv across one ohm = one ma" . When two like value resistors are paralled their resistance is halved, like wise if two resistors are in series their resistance doubles. I cant tell you what they were t...

I just bought my second JMD-1. (Both used but good shape). I really like these amps. My question is: the one I just got, I was checking the bias and noticed someone had paralleled a second resistor over r48 and r49 with what looks like the same as the original resistor. Does anyone know why anyone w...
