I've had this Peavey TKO 80 since the early '90s and in the recent years I decided to restore and upgrade it. Now it's done! a) Piezo tweeter with on/off switch b) Extension speaker out c) Casters d) Metal grill (gorgeous!) e) Camouflage plastic fabric (absolutely wild!) Enjoy! http://www.andresdemarco.com.ar/peavey.html ANDRUCA P/S: Also got a TKO 75 yesterday and I plan on doing the same upgrades and refinish, but converting it to a 2x10" (with Eminence Alphas, I think).
