I bought two of these from Sweetwater but they just did not work for live gigs. They are loud I think I paid $175 each

The ⁠Electro-Harmonix 44 Magnum is an ultra-compact, pedal-sized 44-watt solid-state power amplifier designed to drive passive guitar speaker cabinets. It allows guitarists to bypass traditional, heavy amplifier heads by placing a gig-ready power source directly onto a pedalboard. [1, 2, 3, 4]Key Technical Specifications

• Output Power: 44 Watts.
• Impedance Compatibility: Drives 8 Ω or 16 Ω cabinets. It is unstable at 4 Ω.
• Controls: One Volume knob and a Bright/Norm toggle switch.
• Input Impedance: 2 MΩ.
• Power Requirement: Comes with a specialized 24VDC/3A center-positive power supply. [1, 2, 3, 4, 5]

Core Features & Functionality

• Natural Saturation: Provides clean, flat headroom at lower levels but delivers true power-amp overdrive and Plexi-style saturation when cranked past 10 o'clock. [1, 2]
• Bright Switch: The "Bright" setting applies a subtle top-end presence boost to define the high frequencies, while "Norm" keeps the signal flat. [1, 2]
• Pint-Sized Portability: Fits easily in the palm of your hand or a briefcase, weighing less than a pound (around 200 grams). [1, 2, 3, 4]
• Instrument Versatility: While built primarily for guitar cabs, its flat power layout makes it compatible with any electric-powered instrument. [1, 2, 3, 4]
