The cover for my Cornford Carrera arrived last week, sorry I've not been it touch sooner, just want to let you know that as always it's superb. Absolute perfect fit. No comparison to the shoddy UK made cover that I managed to get rid of on ebay! Thank you so much. I will recommend Studio Slips to everybody that will listen!

I know how it feels to get positive feedback for a job well done and I almost forgot to send some your way. The slipcovers you made in February for my Tweedyverb & Gries 35 amps turned out great ! They both fit very well, look great and seem to made out of a very nice material. Very sturdy for a mere slip cover. And thank you so much for working with me on the new dimensions for the Gries amp. It turned out great. The only adjustment I would make would be to increase the handle opening width from 6-1/8" to 6-3/8".

I just wanted to thank you for making great covers for my Peavey monitors that I ordered through Juniors Music. They fit perfect and the material is awesome too. I enclosed a couple shots of one for you. Thanks again!

Greetings from England! Back again with another order... I must stop buying amps. Thanks for all your great service.

Wanted to let you know how much I like the amp cover. This cover offers all the protection I need and the exterior isn't showing any signs of wear. We play about 7 to 8 shows a month - club dates to concerts and just about everything in-between. This cover holds up and makes it so much easier to transport my amp. So bottom line is I'm more than satisfied with my Studio Slip. Heavy touring where equipment is getting a lot of abuse can justify road cases but for everything else, I think this is the way to go. The quality, workmanship and attention to detail is top notch. I will order again as soon as the need arises. Thanks!

Great clamshells- if you put all the other cover manufacture's and a sewing machine in a box and rattled them around for 50 years it wouldn't come out this good! Great fit! Thank you-Pics enclosed of custom sized rig.

It's bin a while ago but I was on a Holliday. I want to thank you for your superior craftsmanship and I'm not overreacting here. The vibebag you made fits like a glove and is well protected to. Even the keyboard X-stand fits in the compartment! And the back-straps for carrying are fine as well.

I just received my padded cover for my Suhr 1x12 cabinet. When I ordered I had tweaked your measurements as my cabinet dimensions were slightly different. Anyway an absolute perfect fit. Also, the cover quality and construction is great. You have a top notch product. I will not hesitate to recommend your company to anyone I talk to that needs covers and will be ordering from you again when the need arises.
