Just emailing you to let you know that the clamshell cover for the RedPlate BlackVerb got here and fits like a glove, just like my other two covers. Thanks a lot and Happy Holidays to you and yours.

Got my brown Clamshell cover on 10/23/2009. Put it on the amp, zipped it up and worried no more about bumps and scratches during schlepping and non-schlepping/storage. I?m very glad I got the brown ? so easy to tell which of my 12 guitar amps it is! And also glad I got the double thick padding decreases my bump and scratch worry by a factor of 2! I can already tell the leather pads on the bottom were a good choice. I have Tuki covers for all my other amps. I didn?t hear about Studio Slips till I got my brand new Dr. Z amp ? from the link on his website. I prefer the zippers on your covers to the very loud ripping noises of the Tuki?s Velcro.

Once again a word of thanks for the 4th custom cover that you have made for me (it fits dead nuts, exact, right on the money as usual). Now I have to draw up the dimensions for the 5th custom cover that I need for my collection. Thank you much for these fantastic heavy duty covers. They are the absolute best......

The cover for my Dr.Z is perfect. Thank you for the great work and for being a pleasure to deal with. It is great to see a small American company. I hope you guys are doing well.

My Maverick 112 slip cover arrived the other day. It fits snug and I'm happy with the options. The strap pulled the cover tightly down and the pocket is just the right size for a chord and songbooks. I hope not to hit doorframes too often but the double paddling is good insurance. I'm also glad that the brown is a different shade from many of the less expensive ones. It looks and feels top shelf. Thanks for the great customer service.

Thanks Susan. The slip arrived and is great as always.

My amp slip arrived yesterday and it's fantastic!! The handle slot is in the perfect spot and the flap over it will work great for keeping my amp clean. Love the front and back pocket as well (and my wife likes the fact that they help keep our living room a little bit less cluttered with books, cords and wires). Outstanding job on this one...

The case for my Vox DA5 Amp is absolutely perfect. Truth be told - the case costs more than the amp itself, but I needed a simple carrying case with adequate protection. Thanks for the quality work.

Thank you, thank you, thank you, thank you, thank you!!!! I just got home from rehearsal and the case arrived. Wow, you really blew away my expectations, the case is absolutely fabulous and fits perfectly. Thanks again for ensuring I received it before the weekend. I'm playing at a street fair, and will likely have to park some distance from where I'm playing, and the case will definitely protect my amp while it's on the cart. I really appreciate it.

Just want to let you know that my covers came in and fit perfectly! I gave you some measurements for the handle cutouts that were different than what you had supplied for the Fender Rumble 410 and 115 cabs. The measures and your output are dead on. I included a photo of the handle cutout's fit on the 115. The 410 looks just as good. I showed my band mates your slip covers and they were quite impressed with the fit, quality and padding. So glad I invested in your Studio Slips.

Fifteen covers and not a stitch out of place! Even the one for the Mackie (808S) head fit perfectly. My gear is very happy. Thanks again.

Got the cover yesterday. Thanks very much. It's perfect. Protection for the best amplifier I've ever used (you can tell your husband!) You were right, the double padding doesn't really add any weight at all. Short of a full flight case this is going to guard against most of the knocks that the amps likely to get. I'm sure I'll be ordering things from you in the future. And will reccomend you to anyone who's looking for similar things.

Got my studio slip case for my Peavey Custom shop 212 cabinet today. Took it out of the box and put it on cabinet...and, as always, it fit like a glove!!! I cannot express my thanks and my appreciation for the quality job you do with your product. You are always my first suggestion to any on my musician friends who are looking for a slip for their equipment.

I just wanted to let you know that I just got a chance to try the cover on my Boogie and it looks awesome and fits fantastic! The handle opening is perfect! I am very pleased with your work. I will not hesitate to drop your company name when people ask me about this cool cover. I love the zippers! Nice! I hope to do business in the future with you again! Thanks again for your great personal customer service!

I currently own a studio slips cover for my Vintage Sound amp and it is beautiful. I have owned other studio slips covers in the past and have owned Tuki, D2f and others.... The Studio Slips is , by far , the best.

Hey Susan, great job on the cover for my Swart SST-30 head and cab. I have so many cabs and amps if you could ever make a red color as well as the brown and black that would be great!!!
