I was at a local music shop (ok, I admit it was Best Buy), and out of curiosity, I picked up an absurdly expensive Gibson Les Paul Traditional from the wall-o-guitars, plugged it into a Vox Night Train, and gave it a spin. I’ve never really given the Les Paul guitars much attention. Despite their iconic status and near ubiquity, I’ve always thought the Les Paul was just too heavy to consider. But… More

- same preamp and power amp tube complement (3 12AX7’s and 2 EL84’s)
- same two channels: Normal and Top Boost.
- same tone cut and interactive EQ controls
- same weight – 48 pounds. Handwired is larger but birch plywood is lighter than MDF
- same AC15 legacy and tradition
In part one of this, video I explain what treble bleed is, and how to evaluate and select the right cap. I demonstrate my G&L ASAT III which has a treble bleed cap on the master volume, and I compare that with my Epiphone Riviera P93 which has no treble bleed caps (yet).
The caps I tried are (as shown left to right): Silver Mica 100pf, 390pf and 1000pf, a tiny 1000pf ceramic cap, and Sprague Orange Drop (polypropylene) 1000pf, 3300pf, and 6800pf.
The tolerances on the caps are a bit all over the place. I measured the 1000pf caps on my DMM and all were closer to 1250. The 100pf silver mica was over 250! This is assuming I can trust my Mastech DMM.
