Zach at TITAN amps did his SLO100 lead channel mod on my JCA100 a while back. That combined with 4 JJ's KT66 power tubes really helped wake this (already great) amp up a bit more on the lead channel.
I'll continuously post updates and clips of profiles I make of this amp. Lots of cool tones in it. This is just a quick profile of the lead channel with the gain at about 10 o'clock.
Profile is uploaded to the rig exchange. Cleans up really really well using the gain knob on the amp. Surprising considering the real amp can't even do that!
