Love this Mod! Simple but very Powerful!!

Waylon, can I just try various caps at that point without having to change the Resistor value? Thanks..

Your channel is fab. The Ep3 really keeps the character of the pickups. The single coils sounded bold and clear. BTW, mid 80s London met a Mr G who used to work with Vox building cabinets. Mr G told me that the Beatles had Fender style circuits modded into their Voxs. If it's true this must be one if the steps to getting there(Mr G was basically hinting that the Vox cabs the Beatles used had Fender amps inside). Don't know if it's true but I was a young sprogg and at that time very few players even knew how to change a V1 or what type to use...so it was all voodoo to me! Keep reminding us all about "Safety" every video, even experienced Technicians can be distracted or forget.Thanks again.

Cool mod. I actually made an amp where each stage can be tuned with switches for cathode bypass cap and bias resistor. Combined with parallel / series v1/v2 switch, it can get a wide variety of tone.. a kind of analog tube modeler in a sense;-)

WAYLON, Look into the Bernie Marsden Marshall mods they changed the capacitor values which make it has extra bite per each stage which sounds really good. Make a video lesson about it, its simple just the coupling capacitor values are changed per each stage. EVH Jose Arredondo mods using silicon diodes around V1 tube is also an easy mod which you should look into doing a video lesson about it. This diode mod was used for Mick Marrs Motley Crue and many other 80's guitarist.

Good to know. Before the 80s all this was handled by a "Tech" who spent most of the day in a little room in a Music shop or Factory and no-one wanted to fix thier own gear let alone mods..most of the tones we like were created by lucky accidents.

The EP3 mode sounds really good! Very inspiring video!

Cool mod. I’ve got a Peavey Classic 20 mini head I’d like to do this with.

[@WaylonMcPhersonGuitar]

Cool! Let me know if you try it!

[@liquidsmokemustang1537]

@ Will do. I like the Peavey stock but, adding the Fender and EP tone would be pretty cool. You didn’t cover the switch so I just need a SP3T and the corresponding caps correct?
