![]() ![]() To feed these advanced processors we coupled 4Gb of blazing fast PC1600 DDR3 memory, hundreds of Mb of FLASH memory, a proprietary FPGA and a rich set of peripherals. ![]() These processors are the most powerful DSPs available delivering over twice the performance of the DSPs used in our previous generation products. Two 1.25 GHz, floating-point “Keystone” Digital Signal Processors (DSPs) comprise the main audio engine*. Continuing the legacy of this philosophy the Axe-Fx III harnesses the power of no fewer than four separate processors. The Axe-Fx II expanded on this concept by putting two of those same DSPs to work. Leveraging the power of this DSP allowed detail and realism that no other product had previously achieved. I'd buy a AX8 if it was more flexible in it's foot switching, but alas it can't do what I need (3 looper switches and 5 scene switches without changing modes).The original Axe-Fx upended the industry by being the first device for musicians to put a military/industrial-grade DSP into a consumer product. The TN tube power amp sims that really wake up the Ultra's preamps IMO, but of course it's subjective. The TN cabs are about the same as the Ultra's (roughly 2048 point), which is more than enough to capture the freq response of a cab (use a room sim for room tone etc). The Torpedo CAB holds 500 standard IR's, and 32 Two Notes cab sims with real-time adjustable mic positioning, reverb/room sim, tube power amp sims (single ended and push-pull E元4, 6L6, EL84, KT88), and comes with a software editor and IR capture/mix software, plus the WOS III plugin. ![]() I typically use the Ultra with various tube preamps, but also with the Ultra's modeled guitar preamps when I need to travel lighter etc (along with the T_CAB). Nope, definitely not placebo, try it (I've owned the Ultra since it first came out, and have modeling experience from the POD 1.0 thru Axe II/KPA etc, plus I see no need for the the so called Ultra-Rez IR's (just a standard IR with a decimated tail). It doesn't really bloom as good as the Torpedo's tube power amp sims, but aside from that easily as good seeing that this is all subjective in nature. I've tried it with relatively clean through edge-of-breakup Fender/Vox, to pushed mid-gain modded Marshall/Mesa type tones with good success. Leave the Tube-Pre's gain at zero and make up gain elsewhere as needed (Level, FX Loop etc, you ll need quite a bit). ![]() I set the Tube-Pre's gain to zero, Master Volume to ten.Ĭ) I then turn on the Tube-Pre's power section by turning Sag up from zero, and while leaving the Tube-Pre's tone stack flat, adjust the various power amp parameters to what I need considering the gain structure and tone of the tube preamp, and the selected tone stack in the Tube-Pre (I'll look at the modeled amp's power amp settings for ideas and tweak from there etc). The Seymour Duncan Tone Stack Calc for Windows works well for this!ī) I then instantiate a amp block with the Tube-Pre, and then pick a tone-stack for my rather flat sounding tube pre. I usually use my Ultra for FX only with tube preamps and the Two Notes Torpedo CAB for tube power amp sims (the Ultra is much more powerful than a AX8!), but when I go lighter the Ultra's guitar amp preamps sound quite good with the Torpedo CAB as well).ĮDIT: I've found a way to use the Ultra's Tube-Pre for a pseudo tube power amp sim with my tube preamps which now sounds as good as the Torpedo's, and here are the details.Ī) I set my tube preamp's tone stack as flat as possible (typically bass and mid up, treble down, but it varies). For those still using an Ultra, I've found when using the Ultra's Amp Blocks that defeating the power amps, and replacing them with the Two Notes Torpedo's tube power amp sims offers a big improvement "IMO" (it's subjective, but much better feel, bloom, and pick response when driven "IMO"!). ![]()
