From the listing

Seller's description

2013 MIM Blues Junior, 15W, 1x12 combo, Lacquered Tweed Cabinet, with mods and extras! I installed extensive modifications to this to give it the ultimate in sonic flexibility! - Fromel tone stack and power capacitor upgrades - 3-position switch for off/standby/on - Replacement faceplate-mounted Switchcraft input jack that won’t break - Billm Adjustable Bias Potentiometer set to proper bias voltage - Billm Presence control – with cut or boost from stock - Billm Clean boost – pull up on the presence knob to add more clean headroom - Billm "Sparkle Control" High Cut Knob – tweak the “sparkle” anywhere from below to above stock – pull up on the knob for default/stock sound - Billm reverb control pot – audio taper (makes the reverb knob useful from 1-10) - Control panel overlay with black/white letters – the original faceplace has black on silver, which is impossible to read in any lighting situation - Reverb footswitch jack (per Billm)  NOTE: this requires a shielded guitar cable connected to an on/off footswitch button, because the reverb preamp signal goes through the cable - Premium tube set.  Only used about 30-40 hours!  I am also including a matched pair of EL-84 output tubes (per box) and also 3 12AX7 preamp tubes as spares. NOTE that the 12AX7 boxes are not original, 2 of the 3 are generic Chinese tubes from another amp, and one is an Electro-Harmonix tube.The Premium tube set I bought when I got the amp is IN the amplifier, and these are spares.  All the Billm mods are documented (Bill passed away and the business no longer exists) and I can provide the PDF files if desired. Will pack with care. I can remove the tubes and pack separately or leave them in, it's up to you!
