Just had this delivered. After the initial tone tweaking (I was looking for tight bassy lows and a very slight mid scoop and glassy but not harsh highs - a good slapping tone and fingerstyle sound imho) I began to despair- the glassy highs I was looking for were hard to find. No ammount of eq'ing could help, it just sounded a bit honky.. Then I thought 'What if I go through my Boss Lmb-3 pedal? turn ENHANCE up about 3/8ths? hey presto, the perfect tone. I am constantly made aware of this pedals usefulness. Glorious. Now my sound is Perfect. well done to Hartke for an excellent amp (no enhancer though..) at a reasonable price! Have any of you had similar experiences with enhancers? or am I the only one!?
