Great communication, fast delivery and these f-its fit a treat. Make a rubbing and get yourself a pair you will not

regret it.

Outstanding customer service and a great turnaround time. Had a pair of feedback blockers made for my upright bass, and it has been the singular most helpful aid as far as combating feedback goes. They are also very hard to notice unless they are pointed out to you. Highly recommended.

Got some of Bob's f-its the other day for my Gibson Les Paul, they fitted perfectly and reduced the feedback immensely, thanks Bob, your a star!!

Mark  (Middlesbrough U.K.)

 

Awesome.... perfect fit and helped ease the feedback from my guitar, wish I'd found them sooner

Paul (Wigan U.K.)

 

Well those certainly work! They’re a really snug fit with the flanges clicking into place nicely.

Before fitting them, I set up my bass rig, and took the settings up to the point where I was starting to fight feedback. After installing the blockers, I could easily take the level up significantly higher and with better tone too.

Great Service Bob!
I received my double bass F-its in less than a week of posting the rubbing. I’ve had a go at making these myself in the past but Bobs blockers are a professional product and work far better than my homemade efforts ever did.
And nobody else noticed them....

Hi Bob,
I have received your F-its today; I’m very happy, they fit in the F-Holes of my instrument perfectly and seem to work very well (I’ll test them live as soon as possible).
Great purchase, thank you!
Best regards

Hi Bob,
 just a quick note to let you know that the F-its have arrived safely and they are a perfect fit. I’ve not had a chance to try the double bass with them fitted them through an amplifier yet but I will do soon and report back. I can’t get over how good they look on the bass, you really can’t tell they’re on there. I’m really pleased with them and thanks for getting them to me so quickly. From making the rubbing to receiving them from you in less than a week is outstanding service! Thanks also for all the helpful advise prior to me placing the order with you.

Hi Bob,
They arrived yesterday. Fit perfect. Look great. (a lot better than my socks that I was using).  Playing next week so will give me good opp to see how it goes.

Bob
I had my first chance to use them last night on the first night of a tour, and they fit and worked great!  I didn’t have any feedback problems at all. Thanks!
