Theta Preamp Distortion Pedal with Decimator Noise Reduction Review

Excellent high gain tone

As far as I'm concerned, ISP is the champion of the high gain arena. The Theta, in all of it's variations, is a tone machine. Do not let the pedal format fool you - it's the same tone from the head and rackmount preamp. Fender cleans are available in the preamp section, searing Mesa Rectifier and mod'd JCM800 tones are easily dialed in when distort 1/2 are activated..and then of… read more course you have the option of cascading the preamp into the distort channel acting as a built-in overdrive. I don't see myself ever getting rid of this pedal and as a result I won't ever need a tube amp again.

Wow!!! Amazing

Thought about trying The ISP Theta pedal for a while. I have used tube amps for years and did not think I would be that impressed,But I was. I can honestly say I have given up the tube amp thing for good.Love the fact the ISP products are made in the USA. I like to use an american made product when I can. I will be purchasing a ISP Theta Pro in the very near future. ISP products… read more are worth every penny.I have an original Decimator pedal that I have used for over 10 years and a Vector 210 sub. Fantasic products. I'm a ISP fan for life.

Pro Guitar tone and boost

Gain 1 is smooth at 30% then special at 65%. Gain 2 is thicker more deep, also staggeringly good at 30% and 65%, different but good. Very professional piece for lead guitar fanatics. I also used the Preamp/ clean channel as a boost for the Sans Amp PSA-1 distortion and it is the best, very full and balance, the best sound and tone I had been looking for in a long time. Face… read more melter metal and Rock full balanced lead tone. Pedal has a mid scoop that nails it perfectly for snap crackle and pop. Make sure to get a good tube amp and good effects rack. You won't be sorry.

Perfect for 80s rock and metal

I bought this thing for days i give my seven stringed guitar and my modern metal style a break and play some good ol hair band style on my six string, and does it do 80s PERFECTLY. I was able to get awesone def leppard like rockman tones as well george lynch like tones....truthfully, it can do any style. And this handles solos better than any other pedal or many amps i tried.… read more Hooked straight into my peavey 6505 mh power amp section via effects loop return through a 2x12 and it sounds amazing, even hooked it to my old junk crate practice amp and it really polished that turd. I was even impressed with the clean preamp channelnas it handled my high output sd nazgul pickup without any breakup (my tube amp clean channels cant handle high pups). My only minor gripe is that u can't change distortion and clean preamp channels fast as when u disengage either it goes in bypass, or it combines both channels when engaged(not sure why u would want to do that) so its a bit of a tap dance if u want to switch in between them

Hot Judas Priest Marshall Sound, from Defenders of The Faith!

If You're Familiar with Judas Priest' Legendary Metal Marshall Amp Tone from their "Defenders Of The Faith" album, "Some Heads are Gonna Roll", "The Sentinel", "Jawbreaker" "Love Bites", etc, for Me, with My Guitars, Humbucking Pickups, and Ears, I usually always end up adjusting the Theta Pedals Distortion and Active E.Q. into somehow Sounding almost Exactly Like, or Very Familiar… read more to the Sound of a Hot Raging English Marshall, Heavy Metal Tube Amp Tone! Pretty Much Exactly Like the Hot Marshall EL34 Tube Heads Glenn Tipton and KK Downing had Used During Judas Priest' "Defenders Of The Faith" Recording Sessions.But that's just Me and my Ear and Gear, Your Experience may differ, Don't get me Wrong, this Thing Is Capable of Massive SLAYER "Seasons InThe Abyss/South Of Heaven" Type, Crazy Man Thrash Metal and Death Metal Tones as well as other Hot Marshall EL34 Tube, Lower Gain, ZZ TOP Billy Gibbons Type Marshall Sounds and Coolness as well!
