I built this amp a few years ago. http://valvestorm.com/sites/default/files/100_WATT_PLEXI_AMP_KIT.pdf I used Merren iron and I think I used everything listed in these instructions as far as caps and resistors. It sounds awesome, but I've recently seen some Youtube videos of the stock 1959SLP reissues that have just a little more gain and mojo. This one here has me really jonesing for this exact amp. What changes do I need to make to my clone build to make it sound like this. Mind you, I often play at full tilt, have nice speaker cabs, Les Paul, etc., but want to sound like this before coloring it with a pedal.
