The DB750 is definitely, and shall remain number one - you're right it is heavy but just sounds immense, I've got a Trace RAH600SMX that I'm thinking of moving on, it's been a back up to my back up🤣 for a while now, incidentally the back up is a MarkBass F1 with a Sansamp GED2112 used for tone shaping - the back up sounds great and there's nothing wrong it.
It's weird, I've been completely GAS free in respect of amps until I joined the rock band, the DB has that covered completely, but somehow the GAS has returned? Maybe I'll try the Tonehammer, but sometimes it's nice to have a bit of a change.
My head says stop gassing but that's easier said than done🤣
