My beloved Trace Elliot AH300 is out of commission I am hoping to get it repaired, but a super busy gig schedule puts me in need to have something now. Fortunately, I have a great relationship & excellent credit with a local music shop. This does somewhat limit my choices, but I will have a few great amps to choose from. I will be test driving the following- GK 400RB MK IV Hartke HA5500 Hartke LH500 TC Electronic BH500 I am using a Hartke 410XL cab for most gigs, and also have a 115XL to add for the bigger stages. Of course, I know it will be a matter of what I feel sounds best, but I would like to hear from the TB court of opinion about these 4 amp choices.
