Midrange! Your Gio should have tons, and I liked the 'wah-wah on' suggestion. Have a play around with small tube amps and see what you might find- wind the bass off 'till about 9 o'clock, treb on 12 o'clock, mid and master vol. cranked, with a little bit off fizz on the preamp vol. A 15-20 watt tube amp should give a pretty good impersonation, like a pro junior or classic 20. It would be an ideal step up from that Ibanez practise amp!
