AXIOM EFFECTS - Analog Power Amp Emulator (PAE-2) 2026

Like New/Mint for Casey's latest drop! It's in the exact condition I received from Axiom. It has a maximum playtime of 10 hours.

Unfortunately, something has come up for me. As this was the last in and is not yet fully integrated into my board, it is the first to go.

Because you are reading this, you likely know this unit, its reputation (which is well-deserved!), and how difficult it is to obtain. Casey does not special-print boxes for his creations, so this will be in non-descript packaging.

The PAE-2 gives you that cranked-tube feel at lower volumes, or makes your stiff, high-powered head feel more compressive and reactive.

• 100% analog circuitry
• Runs on standard 9 Vdc adaptor (2.1 mm, center negative)
• Captures the dynamics, compression, crunch, distortion, and rich harmonic content of a tube power amp
• A MASTER control that adjusts the signal level into the internal phase-inverter emulator circuitry (just as a tube amp does)
• A FEEDBACK control that adjusts the internal negative feedback level:  From no negative feedback at all (like a Vox AC-30) to a high level (like a clean Fender).
• A POWER control that adjusts the behavior from that of a low-headroom 5W amp to a higher headroom 100W amp.
• A TUBE control that mimics the dynamic compression and headroom characteristics of different power tubes.  You can dial from the stiffness and immediacy of ultra-linear configuration to the compression and bloom of EL84s.
• A PI GAIN control that adjusts phase inverter gain from 1 (like an underpowered single-ended amp) to 100 (a maxed out 12AX7/ECC83 long-tailed pair)
• A RECTIFIER control that mimics the power supply sag from completely stiff, through solid-state diode rectifiers, to the full-on sag of a 5Y3 tube rectifier.
• You can set the PAE to achieve the tightness and bass response of fixed-bias amps or the compressed, spongier dynamics of cathode-biased amps.
• Select single-ended or push-pull configuration.  When combined with the BIAS control, this allows you to adjust the balance between odd and even harmonics.
• A BIAS control that adjusts the bias smoothly from cold bias to hot (centrally biased).  You can go from famous Class A clarity to the bite of Class AB operation (even produce cross-over distortion).
• PRESENCE and RESONANCE controls that operate off the internal negative feedback line, just like in an actual power amp.
• Features an internal trim pot that adjusts flyback voltage spikes in the audio waveform as produced by a tube amp's output transformer and speaker voice coil (or dial flyback out to mimic a purely resistive dummy load, ala the Hot Plate or other resistive attenuators).
• Internal dip switches to set how the PAE-2 responds to the speaker/cabinet/attenuator load.
• Individually handmade
• True bypass
