I use 100w Marshall with 25w Greenbacks 4x12 and Gibson/Fender guitars.

I would like to try TREBLE BOOSTER, but I can't buy and try them all on my own.

Please, tell me, what do you think I should go for and why. I'm not after antique pedals, clones are OK I think at this stage, but I won't mind to learn more about first boosters.
I hope to get feedback here to help me to make a decision what to purchase.

Rock will never die

the beano boost is a really nice sounding treble booster but it also allows you to boost mids and bass. Its really versatile, well built, and mike provides great customer service. There are also clips on the site so check them out.
