ESS AMT-1a - $500 (Hilton)

Took these in on trade for upgrade to new system.
They are used, cabs in good shape, i have the original grills and they are rough to say the least.
I was interested in just rebuikding them, but now other projects demand capitol.
I hooked them up once and they did not seem balanced, all four drivers were working but there definitely was a balance issue.
I really wanna rebuikd them, so im half heartidly putting them up for sale, please $500 is firm, i really dont wanna sell them Lol, so i wont take less, thank you
