I recently purchased a Roland A-88 controller keyboard for use in my live setup. I wanted to protect it when transporting from home to local gigs but, since I purchased it in no small part because of its slim dimensions and relatively light weight, did not want a gig bag that was bulky and ill fitting with unnecessary pockets, wheels, etc. So I happened upon the Studio Slips website, liked what I saw and read, and contacted Susan. She was friendly, informative, and VERY specific about dimensions, double and triple checking with me and my trusty tape measure. I received the bag quite promptly, well in time for my first gig with the keyboard, and when I went to put the keyboard in I initially thought it was going to be too small. Turns out it fits absolutely perfectly without a bit of slop. Great construction, just the right amount of padding. I couldn't be more pleased! I'll never buy a stock gig bag again.

Just a quick email to say thanks for the Clamshell gigbag and dust covers I ordered recently, they arrived safe 'n sound and are a perfect fit :) Very happy, the quality of your work is impeccable! Incidentally, I work for Pro Audio Supplies in Australia, national distributor for Mesa/Boogie down here. I discovered your company from a very old Dual Rectifier slip cover with your logo on it that I found in our inventory a little while back, how 'bout that! I have recommended your company to some friends (and customers) so I hope you see some orders coming your way from our neck of the woods :) I'll likely be ordering more from you too.

I received these yesterday and they are magnificent - sturdy, quality feel, fit perfectly, and are beautiful. My oldest amp (1959 Fender Tremolux) is especially grateful for its first good cover! Makes me kick myself that I didn't order covers for my other three amps -- but that will have to wait a little bit :( I'm so happy I ordered these from you -- they're great! (And I especially like the brown).

Today the cover finally arrived! It fits snugly. I do especially like the way the handle area is covered with the small part of fabric going underneath the handle. :D So thanks for the great service!

My name is Justin and I play guitar in the band Ellery, out of Cincinnati. I ordered one of your clamshell gigbags (in brown!) last year for my mid-70s Fender Princeton Reverb, and have been touring with it ever since. I've always been meaning to write - oh my gosh do I love this bag for my amp. It fits perfectly (!), is very protective, and looks great (I love the brown!). It really is one of my favorite things - such a perfect combo of form and function. I tell everyone about it...Thanks for your great product, it's such a blessing for what we do.
