Currently I've got four amps; Eden WT400, Markbass TA501, Markbass F500 and a TC Electronics RH450. Three cabs, all Bergantino's; AE112, HT112ER, EX112ER (the last two I run as a pair). I've just ordered another TC Electronics head (a Classic 450) so I can link them for more control into my HT/EX cabs using just the power section of the Classic head - running one head per cab.
