This amp has TONES of TONE!! I've had mine for four years now and play usually two shows a weekend sometimes four. No Joke. It still has so much volume, and I'm not referring to loudness which is without question loud! I'm referring to the expanse of the concussion and reverberation of the bass. I always say I don't play this bass, I feel it! On a normal basis I use the PR410HLF cab but when I really need to kickstart the earth's core and make everyones amps almost fall over I'll pair it with the SVT-410HE - Forget about it!

I love being able to control my mainline out and stage volume seperately, EQ works great, Compression, I keep low bout 1/4. Brightness really does just that.

It's all right there. Not complicated or full of gadgets. It's a Bass amp, ya just gotta find your tone. All I've added was a KORG Tuner and the BBE. Set it and forget it.

It's a MAC Truck, has taken disturbing drops in the rack but never a glitch.

Not cheap but ya get what ya play for.

? Support for what ? Happy customer from the first day I rattled the house.

Great looking in the rack.

Great sound quality and versatility. I'm using this amp for hard rock/blues, and could not be happier with the sound. Especially with the gain cranked up a bit for a little "growl".

The only complaint might be that I think a foot switch should have been included for the price. I'm not really using this feature, however, so it's no big deal. Also, the amount of output options on this amp is incredible. Probably more than I would ever need, but it's nice to have them available.

I've only had it for a few months, but it seems to be built very solidly. I've got it mounted in a ten space rack which took a spill from the top of a speaker stack during a show (from the massive low end vibration and poor stacking on my part). I finished the set with this amp laying upside down on the stage and it never hesitated at all! The rest of the band and the sound engineer didn't even know anything had happened!

I guess this amp can be a little pricey for some (myself included), but you get what you pay for and I feel this was money well spent.

I've heard that it's good, but I've had no need to contact them yet.

Awesome sound, temporarily using it with a small fender cabinet w/4-10's and this amp really enhances the sound quality. Quick response and great control. Features abound and this really makes live bass sound like recoreded base. Even the rest of the band leaned toward my gear at the first gig, and said... "That thing really kicks". A tip with this amp... play with the adjustments, and turn the bass guitar all the way up to allow full instrument tone, adjust the "Gain" until the limit light blinks, then adjust final volume with the Master. This made a major difference with my Rudy Sarzo Bass gutar.

Great look on stage in my rack mount. Looks to be built like a battleship. But I'm particular about my amp rig, so it will not be stashed in the equipment truck. Instead it will go home with me.

Wished they had a customer service line on Saturdays. I had some questions and there was no Hotline for me to call for direction.

We play deep dark heavy blues, tuned to Drop C. Of all the heads I have played the 4-pro was far bigger sounding, and had all the punch I look for.

I added the Ampeg foot switch for my mute and for the eq. it is worth looking into, it was the only thing I could think of out of the box that I wished for.

This is a pro head, it took a couple of minutes of reading to understand setting it up, but once I started, it was easy, and it is worth reading, because this head is so versatile.

Crash boom bang, life on the road happens, this head has been thru a ton, and is still working like day one. Worst thing about the 4-pro, its heavy...

Takes a licking, easy to set up, works hard as I do, yeah, great bang for the buck, that = great value in my book.

I have only had one question for them, it was over the configuration of the mono bridge cable, and they were very helpful.

Once I had heard the 4-pro I knew I had to have it.
