The Guitar
Flat-wound 10's and liking it.
The base setting for the dials is "all the 7's", and the pickup selector default position is in the middle.
I experimented with pickup height, and in the end did what would make a well-bred tech shudder, set the heights by tone. The neck is practically flush with the surround, and the bridge is about where a good tech would put it. Switching from neck to bridge does not lose or gain volume - the SPL meter on my iDevice confirms it. All the problems I have had with the characteristic Epiphone Pro-Bucker tone have vanished.
The Amp
I was determined to get that Marshall-ish sound. These are the Panel settings
and this is the all-important EQ setting
The power setting is 0.5W. This is not optional. Neither is the 12dB attenuation. I have no attenuation on the 4kHz and 2kHz bands, because that's where a lot of the distortion comes from.
Use the Neck pickup, turn the tone dial to 0 and the volume to 8/9, play above the eighth fret and you will get that creamy 1960's distortion sound. There's a reason no-one needed pedals back in the 60's. Turn the tone dial back to 7 or 8, and all that crunchy Marshall-ish goodness comes back.
This tone does not play well with anything except the Limiter. But then, if you're using it, you won't want any other effects.
Having done that, I went for the Fender-y sound. These are the Panel settings
And these are the all-important EQ settings.
There's a trick. Just a little touch, the lightest sprinkle, of the distortion effect, to put a bit of bite into the sound and stop it sounding like a sodding jazz guitar.
The power setting is 25W. This is not optional either.
This sound is a base for putting the modulation and time effects over: it isn't really a tone in its own right.
Neither of these sounds are the "dials at 12:00" type, and in fact are quite extreme. If they weren't, they wouldn't be iconic. There's a lesson in there somewhere.
I have simplified the options, the idea being to approximate a pedals - amp - speaker set-up. The Chain has all the effects (except Reverb) are before the Pre-Amp.
Recording via USB
I've tried. Lost cause. Too much faffing around. If I want to record, I'll get the specialist gear.
