I'm transitioning from a 6-year-old Ampeg PF-350. It has served me well, no problems, will now be a backup amp.
My initial impressions of the miniMAX....
- this amp has got some serious slam to it! Very impressive. Notes have a bigger dimension.
- the low end and low mids have great EQ control, great grunt.
- the tuner works well.
- easy to dial in the thick fat sound I like.
- Fan is surprisingly loud. I never heard the fan on my PF-350. I'll have to come up with a fan noise silencer.
- big 'feature' sticker on top of amp was a bugger to remove. I scratched up my brand new amp in the process.... grrrrr!
- Overall I am very happy with its build quality, power, and tone shaping controls. It makes my good sounding Cabs into amazing sounding cabs. I did not really expect going from 350 watts to 500 was going to produce such a dramatic difference, but Peavey did it right!
Kudos to BbbyBld !!!
I also had a PF350 for a while so I know the change you are speaking of. Congrats on the new amp!
