MaxHart85231281734137 Posted September 28, 2009 Share Posted September 28, 2009 i know that you can use old real to reals as a preamp or distortion pedal, i was woundering if i could use my 5watt blackheat head as such a thing for my vox ac30? can i just run the ohms outs into the input of the vox and have a 5watt preamp pedal?

ehedwr Posted September 28, 2009 Share Posted September 28, 2009 IMHO No. The preamp in your Vox is designed for high impedance, low voltage signals from guitar pickups. Amps in parallel sound fantastic but not in series. Why do that anyway? Link to comment Share on other sites More sharing options...
cGil Posted September 28, 2009 Share Posted September 28, 2009 If you're up to it, you could gut it and rebuild it with a small signal preamp pentode like an ef86 or 6U8 or whatever where the el84 used to sit. This would also eliminate the output transformer, so the whole amp would basically wind up being only a preamp. However, overdriving a small signal pentode would get you a distortion much closer to what you get from a pentode power tube, instead of the typical fizzy preamp distortion that is so common. Of course, it'd be easy to get that too by adding another 12ax7 for more gain stages. If you're interested, SEwatt.com has the info you need to get it done. Quite a few folks are playing with small signal pentodes over there, nowadays. Gil... Link to comment Share on other sites More sharing options...
