I finally got the time to do some testing, some a/b comparison of TH2 full version and S-Gear2 by Scuffham Amps. A few of you have been asking how TH2 compares to S-Gear2. To be honest, my evaluation is probably biased as I have found S-Gear2 to be my ideal amp sim for my playing. Yet the comparison I did may not be fair in another aspect because TH2 has a boatload of amps, cabs and effects, and hundreds of presets; whereas Scuffham's S-Gear2 has only 3 amps.
My verdict. If you need an huge arsenal of diverse amps to fit almost any variety of settings, then TH2 may well be very good for you. If you only need one amp sim to do every style, then the versatility of the TH2 may be good for you. Without question it is worth the $99 upgrade from the TH2 Producer.
However, if you are looking for that boutique "hand wired" clean and overdriven tube tone, S-Gear2 still sets the standard, at least for me. To my ears S-Gear2 still outshines TH2 when it comes to the boutique clean, overdriven fusion, satuated blues tones. And to be fair, I focused and dove down deeper by comparing S-Gear2 to the Brunnetti Mercury boutique amp in TH2 and to the Randall Lynchbox (clean, topboost and blackface amps); Brunettit and Lynchbox were good; S-Gear2 is absolutely GREAT/fantastic. The S-gear2 had more warmth, yet clear tone that was still complex and responded to the pickups and volume adjustments of my guitar and to picking and finger articulations. I honestly had to fight to get the TH2 to produce the clean tone that was full and bold, yet S-Gear2 provided this warmth and transparency almost instantly. After a couple of hours of testing, I had come to the realization and had made the difficult decision not to go forward with my purchase of the TH2 Full version upgrade (at least not at this time). S-Gear2 to me still remains the ideal amp for clean, overdriven clean and saturated blues/fusion tones. It is wonderfully dynamic and is like having a hand-wired boutique amp in a vst plugin.
I honestly had thought at first that I would get TH2 Full Version upgrade for $99 because of the Lynchbox and the Brunetti Amps. When I played with it last week and this weekend it was okay and good at places. But when I finally had time to put it through its paces and then openned S-Gear2 and did the A/B comparisions, I quickly realized that all I still need is S-Gear for what I do, for clean, overdriven tones. To my aging ears, nothing still comes close to the tone and transparency of S-Gear2. BTW, I was using a 335 with classic 57 neck and Seth lover in bridge, an ES175, and an American Standard strat, which will tell you that I am not a shredder or metal player. In fact, my ES-175 did not sound too good through the TH2, but TH2 is not for jazz, at least not in my opinion.
This is not intended to be a shot against TH2, but rather my personal take on it. It just does not fit my needs. If, however, I were interested in a metal amp, or hard rock amp, TH2 might well find use, but the one-trick pony overdriven clean amp for me is still my S-Gear2. Certainly TH2 full version is worth the $99 upgrade for the breath and variety of its arsenal, but if you need just one great amp for a wonderful overdriven clean tone, S-Gear2 is still the gold standard in my little home studio.
Oh, for the record, I have GR4 (and GR5 demo), Amplitube 3.7x (with almost all its custom shop amps and cabs), demo of Waves GTR3, and a Vox and Pod Farm amp sim.
So Carl, if you are reading this, S-Gear still reigns king for me.
