Does what it should!

Comments about Blackstar HT Series HT-BOOST Tube Boost Guitar Effects Pedal:

So I happened upon my local Guitar Center during a holiday weekend sale looking for something to add a little dirt to my new butterscotch blonde telecaster. I am using a Crate V200S which has a lot of power but the clean channel is clearly my favorite of the three. It is solid state and supposedly has tube characteristics, but I don't really see it. I recently purchased a ModTone overdrive pedal to provide me with that sound I am hearing in my head, but it still didn't do it. I played through a bunch of different pedals at GC but nothing really did it for me until I asked the salesguy if he had any tube pedals. He brought out the Blackstar HT-Boost, which he described as a clean tube sound, plugged me in and dialed up the drive knob. Voila, there was my sound. By adjusting the drive, treble, and bass knobs, I was able to add just enough dirt to my tele to give me that 60's rock and Bruce Springsteen sound that I've been looking for. And by lowering the volume knob on my axe I was able to clean up the sound on the fly without bending down to the pedal board. The pedal comes with a power supply that you must use (this brick requires some serious power!) Also, two outputs - one into a valve amp and one into other pedals so they will play nice and not cry when this puppy kicks into high gear. I highly recommend this pedal if you are looking to get a real tube preamp sound out of your amp with some grit to dirty up your otherwise sterile sound. It is built like a house and I expect it will give me (and you) years of reliable performances. It is a bit pricey, but it's a lot less expensive than tossing your current rig and buying a $000's Mesa Boogie. Enjoy!

Whoo Weee!

Comments about Blackstar HT Series HT-BOOST Tube Boost Guitar Effects Pedal:

Talk about a tube boost...this is the one. I was skeptical at first because I don't like their amps whatsoever. I heard this pedal at a friend's house thru his 1974X. The Volume was on 2 with no gain comin thru...pedal tap...and it just got soooo sweet. Not the most transparent, but the warmth it added to the 74X(on 2) was just beautiful. I had to have me one! I run it thru an Egnater Tweaker and it just shines on any Tweaker can control the amount of boost, high and low end (no mid control though = 4 stars)...ya might wanna turn the bass down a bit on the pedal if your speakers hold bass real well...can get to be a bit much. All in all, this is a great pedal and would be a good addition to any pedal arsenal.
