Well... what can I say, adding to @Al Krow‘s comments above we spent a few hours A/b big some gear and playing some basses, I echoe the words above as I love my RH750. I’ve used the rh450 upgraded to the 750 for best part of 10 years. I preferred the RH over the DG, having never heard a DG I really wasn’t blown away. My preferences are for the presets and compressor built in to the RH. I’d never use the DGs built in effects pedals. All horses for courses I guess.
We then tried his Mesa M6 Carbine. Wow. What different beast it was. Head and shoulders better, tonally than the 2 class Ds. To be fair you would expect that as the new value on it was double both the other 2. I liked it so much that I was fortunate enough to acquire @thodrik‘s M6 this week. It was put through it’s paces this evening at a gig and it certainly didn’t disappoint in anyway. Fat warm sound but clear and crisp highs when needed, really cut through the mix. It punches hard and purrs like a kitten if you lay back a bit. I couldn’t be happier with the set up (running with a Bergantino cn212)... The rest of the band loved it to, instantly picking up on the sound being warmer, more rounded...this could possibly be my favorite amp to date. 👍🏻
