A true two-in-one pedal that captures the legendary tone of the classic Soldano® SLO-100®.

The SLOstortion brings the awesome tone of the killer high-wattage Soldano heads and famous preamps together into one package, with a voicing that will be maintained across virtually any setup. No need to worry whether you'll have a good clean tone and a good distorted tone. Just your favorite amp and the SLOstortion to take your tone places walked by some of the best guitar-slingers from the 1980s to today.

It features a great three-band EQ to make sure you can have "The Tone" through YOUR setup, whatever it may be. The gain is switchable between two separate modes to capture the nuances and flavor of its inspiration. The normal mode will go from a nearly clean tone to a tight, defined crunch, and the high gain mode goes all out. It's responsive, too, and to top it off, even when the tone is as heavy as it gets, the pedal doesn't squeal and hiss with noise. No sacrifices for your rig.

To top it off, the pedal features a specially tuned clean boost. It's an op-amp boost circuit Brian's worked on for some time, and even at unity output, it will add a little something extra to the sound. Stand out for your solo, or just give it that little extra kick. To complete the package, it functions independently: a true two-in-one pedal, offering great value. It's Wampler's way of showing appreciation for the faith you place in their products!

Somewhere between the classic distortion tones and the ultra-modern high gain sound, there was an American amplifier that redefined gain. Soldano amplifiers have been heard on some of the best guitar-god albums, and Brian couldn't resist the challenge of capturing an authentic SLO-100 inspired tone in a pedal. Brian's refined ear and wealth of experience designing pedals has led him to take what he feels are the killer tones of that amp and bring them under foot for guitarists with any setup.

We think you're going to love this one. Brian's worked on it as hard as he's ever worked on anything before, and the results are apparent: an authentic American roar, with all the gain and tonal adjustments you need to take you and your rig wherever you need to go, and reliability that won't let you down. Rock on, powered by the Wampler Pedals SLOstortion!

Comments about Wampler SLOstortion Distortion Guitar Effects Pedal:

The Wampler SLOstortion is exactly what the name implies: a Soldano SLO 100 in a box. The crunch mode can be creamy and bluesy, while the overdrive mode has enough gain on tap for any solo work you may be doing. I've been using it through a Carvin Belair, which is EL84 based and has a wonderful clean sound. This pedal also loves my ESP George Lynch M1 Tiger guitar.

The most impressive feature on the pedal is the booster, which is massive. It can easily put you over everybody else when playing in a live band.

This is the first pedal that I've used at a gig exclusively for my distortion sound. Typically I use the distortion coming from the amp. That being said, overall I've been very impressed with this product and will be looking into other pedals that Wampler has to offer.


Distortion for sure!

Comments about Wampler SLOstortion Distortion Guitar Effects Pedal:

Basically this is a very good pedal if you can some how eliminate the noise when it's in overdrive
The crunch selection is excellent for playing rhythm but for solo's you need the overdrive,
