I purchased a Studio Slip cover for my Swart AST 6 months ago. From the day I received the cover, I have admired the quality and attention to detail that was put into creating this. It fits perfectly, has a gorgeous inner lining, and provides complete protection including a flap underneath the handle. I also own a Fender 65 DRRI, Buddha SuperDrive, and Mesa Mini Rectifier, that have their own covers, and none remotely compare to this. I will only purchase a Studio Slip cover for my future boutique amplifiers.

Thanks for making perfect fitting clamshell cases for my 60's Fender and Silvertone amps! I'll be taking these amps on the road over the next few weeks touring with Brett Harris on these upcoming tour dates and they'll make appearances in the house band of a popular weekly Flash Chorus event in Durham NC in the fall (among many other endeavors). I'll be directing friends your way for sure.

Susan I received the case for the Carr Mercury the other day. It fits like a glove. I really like the new design. Great job. FYI I also sent an email to Steve Carr telling him how satisfied I am with your products and service and requesting that he add a link to Studio Slips on his website.

Just want to let you know that I received the amplifier cover this afternoon. I really like it! The fit and finish is great; and thank you again for covering the entire bottom in leather at no extra charge. I will certainly be recommending you to anyone in the market for a good case.

Just got my studio slip. It fits so perfectly I was afraid for a minute that it wouldn't fit. There's no extra space in there (which is what you want from a case). FITS LIKE A GLOVE. thanks Studio Slips. was a total pleasure ordering from you.
