Thought you might like to see my modified Matamp C7 - with the reverb removed and a six-position voice switch added. It's made the C7 more versatile. For those that don't know, the voice switch is the same as used on big Matamps, and it progressively reduces bass and gain. Juggling this switch, the tone controls, and the attack knob gives a lot of different sounds. Good for adjusting between humbuckers and single coils. You can really dial in just the sound you need - obviously with the basic C7 character retained as the foundation of the fine tuning. Here's the front panel. I also got a second 1x12. The original cabinet has a Celestion Alnico Blue, and the new cab has a Celestion G12H. I can use them separately or together, of course. I like the sound of two different speaker types together. Sounds absolutely fantastic, and it now brings a glass of beer up to a more convenient height!
