I currently have a Schecter Stiletto Custom 6'er and I want to try removing the high C and replacing it with a low F#. I love the C for jazz/blues, alas I mainly play with metal bands now adays, and with the rising rate of 8 string guitarists it seems logical to go lower. (inb4 Dick from Meshuggah plays on the same octave as their guitarists ) I've read up as much as I can on this site and others and from the research I've done so far I know that I'll need a GOOD speaker to keep the low notes from sounding like farts. I was thinking about buying a 1x15 speaker and putting it in my old crate combo(the head blew out a few months back). So my question is, does anyone have some recommendations for a speaker and just some general advice/forwarning on amplifying a low F# string? Also, should I be looking at any certain amplifier heads? Sadly due to budget restrictions I'm limited to 400 bucks tops for a head. Thanks!
