iSP Technologies brought its new Theta Pro DSP to NAMM. Billed as the ultimate recording and performing preamp, it uses a 32-bit SHARC processor and a cutting-edge A/D converter that yields 124 dB of dynamic range for greater clarity. It comes with 256 presets and an astounding number of parameters to adjust, both in terms of gain, EQ, effects (wah, modulation, delay, compressor, and reverb), cab and speaker emulation, and more. There's also dual XLR and 1/4" outs, headphone jack, and jacks for two expression pedals and a volume pedal. Approx. $1,300 street.

They also brought the super-powerful Beta Bass pedal—a scaled-down version of their Beta Bass head that goes for around $400.
