Merry Christmas, all.
I've just bought a DC-5b combo. I owned one previously, loved it, sold it and went through a JCM800 and a Lone Star before returning to the addictive crunch!
For recording purposes, I rely on the rhythm channel pull boost almost exclusively for a solid crunch rhythm tone and tend to prefer this boosted for leads over the lead channel itself. When setting the amp up this way, I lose the functionality of the non-boosted rhythm channel. This isn't much a problem for recording but I'd like to be able to switch between sounds that are a little closer in timbre.
I've bought some new tubes to control the headroom and open the whole thing up a little and as per my DC, I'll be performing the output volume, blanket and FX loop mods which for me, contributed to and improved on that lead channel opening up a little.
Looking at the block diagram on the first page of the schematic, the tone stack on the rhythm channel is pre-gain, after V1a but post-gain after V3b for the lead. Has anyone modded the lead channel to move the tone stack pre V2 and V3 gain stages that would be willing to share a diagram/ instruction on how to achieve this? It should bring the lead channel a little more in line with the rhythm and closer in operation to the Mark series to my mind.
I'm competent with a soldering iron, offering guitar repairs in my local area and would like to attempt this myself. My amp experience doesn't extend beyond simple mods or changing a resistor/ cap here or there, but there's not really anyone in the area I want to drop this amp to after a few horror stories from the locals.
Any advice would be appreciated.
