Connecting to the external input of a small 15W amp and you can get a natural overdrive and appropriate compression of a tube amp. It may feel similar to a Marshall JCM800 with a Strat or Les Paul, but it's smarter. Each string rings glossy in chords. It really matches rhythmic riffs like of Blue Saraceno. Adding an overdrive pedal, you can make a sound like Eric Johnson. I think the best matching is with a Les Paul, but by carefully adjusting not only the gain but also the tone and level, you can make a wide range of over drive according to a pick-up power. The effect of the variac may seem slight, but it has a very important role in adjusting the nuances of over drive. However, even if the maximum gain, you won't get the sound of a modern high-gain amp. It may not a kind of catchy preamp, but if you like playing guitar and like Blues Saraceno music, I think it's worth experiencing this preamp. Also, basic quality as a product is no problem. Excellent.
