When I originally converted my 2204 to a 1987 I internally jumpered the channels. Then you can keep the faceplate stock and have the two volumes for infinitely-blendable channels.Billy Batz wrote:Email me Jason
I dont know if Id say a NMV has less treble. Its got just as much cut since Im assuming youll have to g for the 69. There just 2 different sounds. You wouldnt think that one thing would change the amps character so much but it does. Im assuming youve tried everything to kill the excess treble?
Having the single bright channel isnt a bad idea. You could have both channel and just internally jumper them so that both volumes are active and leaving a channels volume on 0 turns it off.
You had already changed the treble-peaking spots in the amp, right? (The 470K/470pF combination between the inputs, etc.?) You could always try a bigger cap on the phase inverter plates to kill some high end, I regularly replace the 47pF with a 150pF and have no shortage of treble or sparkle when I need it.
