Going back many pages and posts on this thread, I mentioned issues I was experiencing with my SS3 where there was a discernable "warble" when using a fast rotary sound. I also had issues with low end - so much so that I needed to use a second amp to improve the bass. But I was just never happy with the sound.
I couldn't reconcile this with all the great comments others were posting. So I reached out via email directly to Center Point to inquire if what I was experiencing was normal - and immediately heard directly from Aspen. Frankly, as I had purchased from Sweetwater, I expected to be sent back to them... but no, Aspen spent a lot of time walking me through troubleshooting and testing. I sent him some WAV files of my unit and he agreed something was definitely amiss and IMMEDIATELY drop shipped me a new unit. No "provide a credit card number in advance," he just asked my address and rushed me out a brand new unit so I'd have it in time for a big gig. Which says an awful lot about Aspen and Center Point. I'm still overwhelmed, as many companies would have just pushed me back off the vendor.
The new amp, of course, rocks - and NOW I know what everyone was raving about. I've used it on several smaller gigs so far to rave reviews from both band members and musicians in the audience. I've got some big shows coming up and am really looking forward to getting a chance to crank it up. So I'm quite a happy camper now!
Every company can have a unit or two slip thru QC... that's just unavoidable. But how they stand behind their product says an awful lot. And for the head of the company to get directly involved to resolve an problem says even more.
So I thought kudos for Aspen and company were warranted here!
