Review: The SGT-DI is an awesome pedal/ preamp that sounds great. Is it the last thing you’ll ever need? Probably not, but if getting started or need an additional to your kit, it’s worth it. B15. I have a ‘66 B-15. It sounds exact. I have used the SGT at gigs with my B-15 so I didn’t have to mess around using a microphone. The overdrive channel is great to give that boost and growl B-15 do when turned up. The preamp gives more accessibility to key tones but maintains the touch sensitivity of the actual amp and tubes. SVT. Super close. It’s a legitimate gripe others have commented that it’s not the “best” but it’s probably top 3. Like the B15 setting all the really great tones are real easy to dial in. The OD circuit makes it grind like a stack. Having the B15 circuit makes the SGT my choice. If you only used SVT. Still my choice. Why? Quiet practice. Plugging my iPad in to quiet practice is huge. I don’t disturb my family, I get yelled at by my wife less, score. I didn’t believe I’d use that function much, but I’ve gotten to where I use it the most! Compressor. Boy this is griped about in other reviews. Not the most “useful” but I use it a lot! As an easy one knob compressor, like an orange squeeze or on board mixing board compressor, 100% worth it. The single knob compressor on the SGT does that sweet one knob thing to give more pop. It’s actually the perfect little add. If you need more, get one of the really nice ones out there. If you “need” the extra compressor features, you need the extra compressor anyway. Overdrive to fuzz distortion. The Grit channel is a huge plus. You may play with it on all the time! I love just a real light OD. It stacks with fuzzes well too. Build quality. I did receive 2 as the first had an issue. The first had a loose connection with the auxiliary input for my iPad and the silent practice. It became obvious early the silent practice was going to be a huge beneficial use. I returned and received a different. Longevity. I worry about longevity of cables going in and out, the way the solder on jacks on anything should give everyone concerned on anything electronic. With soldering experience they are easily fixable if you can find the part. But it’s still a big inconvenience.
Review: Es perfecto, el 810 suena genial y el sgt le da un toque especial además me gusta mucho la perilla de medios le saco mucho provecho
