So the first products from Behringer's new stomp box line have shipped, including the 3 SansAmp rip-offs. I got the GDI21, which is a copy of the Tech21 SansAmp G2. I'll post some soundclips once I've gotten a bit more familiar with it, but here are some first impressions and thoughts:
1. Initially, the unit seemed quite sturdy (in the package) and since it's hefty, I figured it must be die-cast. However, upon opening the package, I discovered that it's simply heavy-duty plastic. It's not likely to crack or break, but it's still not a tank, you know? You'd think they'd at LEAST make the switch heavy-duty for stomping activity, but the switch is even flimsier-feeling than the rest. Odd place to skimp, where it's most likely to break.
So, yes, it's durable enough to use on stage for some people; however, if you are heavy-footed you are doomed.
2. When not engaged, the level is not high enough, so using it as an effect to turn on and off seems 'out'. I have to explore more, but it seems to me that there's no way to match the 'clean' level with the 'engaged' level. Naturally, you don't usually adjust the clean level of a pedal, but a clean enough signal should usually pass through. Initial tests seem to indicate that the level is being significantly attenuated when not engaged.
3. The amp sounds are quite good. There's still something 'missing' much of the time, but for $50 CDN, compared to a $2,000 amp, you shouldn't expect a miracle. I was pleasantly surprised!
4. The 2-band EQ isn't flexible enough. In order to get the heavy sounds to sound... well... heavy! I had to scoop a wee bit of the mids. I'm actually a big fan of mid BOOST pre-distortion, and THEN a bit of mid scoop at the end, for heavy sounds. I don't actually like to cut my mids out, I just like to change the way they interact with the distortion. I don't have an EQ pedal, so I had to settle for a cut post-distortion, and it worked fairly well.
5. The drive knob doesn't provide a wide enough range. It gets dirty too quickly (at like, "1", "2" at best) to provide a very broad range of mildly overdriven tones. However, with a bit of finesse I was getting some lovely driven Twin sounds.
6. This is something I should have known, but just didn't-- as a DI box (it is capable of being a neutral DI with ground lift) it is only effective when using the balanced XLR line out. While there's a 1/4" mono out, this is only suitable for chaining it as an effect, not for DI duty. I found I got best results by going guitar-->GDI21-->StudioV3 preamp-->soundcard. Ideally, you'd want to cut the additional pre-amp out of the equation. :? Weird. Again, I can't help but wonder if I'm doing something else wrong, but it's not like there are a lot of controls to screw up. Also, my soundcard is partly to blame because it only accepts unbalanced RCA input. If it had a balanced line in, I might have had a proper match and been able to eliminate the extra node in the signal path.
In summary:
- construction: adequate for the studio but not up to 'real' or 'enthusiastic' stage work
- sounds: surprisingly good, especially with a bit of work! Changing the gain stage models and mic placement models actually had a pleasant (and predictable, meant in a good way!) impact on the tone. Curtis P would be in pinch harmonic heaven with even a half-driven high-gain "brit" sound with centre mic.
- as a DI box: don't think my setup allowed me to properly test it
- value-for-money: exceptional, so far. I'll get back to you after a few days. I need to A/B some GDI21 vs. virtual amp to see if I'm actually getting some worthwhile tone out of it. For people not using or not comfortable with virtual amps, this had GOT to be good VFM.
