Awesome Controls/Sound Quality/Build Quality

Exactly as my review title states. Sound is crisp and the EQ/Preamp/Compression controls allow my Passive Birdsong Bass to pack a good punch.

Totally Blown Away!!!

I can't say enough about this amp! The tone shaping possibilities are ENDLESS! Not to mention it's light too...well I think so but my last amp weighed 90lbs too so...lol. The Hartke HA3500c goes REALLY nice with an Ampeg PF115HE...just throwin that out there...lol. This amp has everything you could want in a very affordable package! Thanks to Nich Magnani for getting me setup with this bad boy...and Sweetwater for getting it here NEXT DAY! Sweetwater for life!

Love This Amp!

I have been gigging weekly for around a year with one of these. Great bass sound when coupled with a Peavey Headliner 4x10. Saw a friend using one, tried it out, and went home and ordered one that day! Solid as a rock, plenty of headroom, and punch. Love this amp. Service from Bob Mondok and the guys at Sweetwater is absolutely second to none. I recommend them to anyone I can get to listen. Great gear and great service! My relationship with Sweetwater has lasted longer than some of my bands, and meant more to me!

Hartke HA3500

My last amp was a GK 400RB. This amp is far superior in tone choices and power, With the dual pre amp, equalizer and contour I can have any tone I desire. Most music I play is best suited for a warm and mellow sound which is easily accomplished. I received conflicting information on weight. I weighted my amp at 23.2 pounds. I believe ultra light weight amps have durability and longivity issues. I believe I purchased an amp with good quality, good sound choices and an amp that will last for years.
