Hi guys, got the cover today and it is fantastic! Fits perfectly and looks great!

The covers came in today. The fit great. The notched backs worked for clearing the plugged in speaker cables. One lies perfectly flat and the other sticks out a little by the power plug. I hope the notches did not add a lot of work. I'd bet there are other amp owners that would entertain some sort of cut out to facilitate hooked up / plugged in equipment.

Your service was first class and the finished product was just as I had hoped… So… Thank you very much. I have passed your name on to others who may require you services.

Everything turned out great! The clamshells are exactly as I pictured, and they make a perfect set together. They load the same way, stack in the same direction, and carry very well. The case for the amplifier head is also great. The double padding makes me feel like it is very well protected and the pocket is just the right size for 2 speaker cables and a power cord. Thanks for a great set of products. You'll be my go-to source for this sort of thing in the future.

Just a brief note to let you know I arrived home from Atlanta tonight, and the dust cover for the 'Reeves Custom 225' bass amp was here. The fit is absolutely flawless! Excellent attention to detail prevails throughout, and I am quite pleased. Your video tutorial helped to ensure that my measurements were properly taken with appropriate care. The finished product is the proof.

The slip you made for my Glaswerks Super Overdrive II amp fits perfectly. The measurements listed on your website nailed it! Now I can gig with this amp and sleep easier at night knowing it is protected. Awesome product-

I just had to let you know- not only is your product the best, your customer service was flawless through my complicated international order, Justin walked me through double checking all measurements, and to top it off- your international shipping was the best I’ve ever experienced. I’m an American living in Germany- it’s really complicated over here with the customs and duty stuff, it can really be a problem. You obviously knew what you were doing and filled out the paperwork so correctly that I was able to pick the package up at my local post office and pay the duty there- I can honestly say, that has never happened before. Normally it gets held up for many days and then I must go to a customs office 45 minutes from where I live, and then wait sometimes close to an hour for them to do all the paperwork and calculations, and THEN pay. Salt in the wound… this was super easy, calculations were spot-on, and the covers fit like a dream and are super well made. I have in my Los Angeles home a bunch of vintage amps, all with Tuki covers I ordered years ago- they were really good, but yours are on another level. I’ll be upgrading there when we have the chance! Just a big thanks, they are GREAT!

I received my Studio Slip today for my Roland Blues Cube Artist, and I have to say I'm very pleased, and very impressed! I've had other covers from other companies, but this studio slip is easily the best fitting and well constructed one yet. The stitching, the cuts, the edges - all perfect and square. I think the only mistake I made was not ordering form Studio Slips in the first place! I'll be ordering more in the future!

Just wanted to let you know the cover arrived here in the Caribbean today ? nice work! Congrats on a good-looking and effective cover.

I just now put on my new Fender Rumble V3 100 watt Dust Cover and it looks and fits just like the 500 watt Clamshell. If I get the 2x10 expansion cabinet and my wife doesn't kill or divorce me, guess whom I'm going to call to make a Clamshell; it sure ain't gonna be the Ghost Busters. The rest of the band are considering ordering some cases since seeing your products. Great job!

You have played a blinder with me case. It fits like a glove and the strap is a big help. Just waiting on my princeton to be done then I will return. Thanks again for your great service. Even with the $60.00 duty it still can't be beaten and we always have a bit of a giggle too!!

The clamshell cover for my Rivera arrived today, just in time for an out of town gig, next week. It also is a perfect fit. just like the one for the Mesa. I now have "matched" luggage for my amps, and I'm sure they will stand out in the sea of black stage equiptment, and I will be able to find them at a glance. I also noticed that I could put a small lock in the zippers, for a little extra security....I will call again...

Just dropping a note to say that I’d received the covers and they fit perfectly! :) Tks!!

Just wanted to verify with you that I received my amp head cover (for a Mesa Express head). The cover looks great - no surprise! Now all I need is the head itself which is being manufactured. In the meantime I'll stare longingly at the Studio Slip cover and just imagine. Again, it's been a pleasure dealing with you.

I just wanted to thank you for the good quality workmanship in constructing my gear-bag. I have not yet had a chance to field-test the bag, but upon close inspection, I am very confident that it will perform according to our design.

Just wanted to let you know that I received the cover for my Vox AC50 head today. The two bonded instantly and appear to be made for each other. As Bogey says to Claude Rains at the end of "Casablanca," "I think this is the beginning of a beautiful friendship." Thanks again for a great product, great service, and great email!

I just picked up the clamshell gig bag from the post office. When I first set the amp in the open bag I thought, 'It's too small!' Then I realized that it was actually snugly perfect. I really couldn't ask for a better fit. Good job.

The cover arrived today - it slipped over the speaker perfectly!! This is my fourth cover that I have had you make. All of them, without exception, have been spot-on perfect in fit, in protection, and in just plain looking good! And, of the amps/speakers I have sold, not one buyer has said that he didn’t want the cover. Thank you for your wonderful work.
