A 300W head with improved features and excellent Ashdown craftsmanship.

Ashdown are proud to announce the launch of the new and improved range of MAG heads and combos. After four years of the current MAG line Ashdown decided they needed a little bit of an update. Ashdown didn™t by any means look to change the wheel of the hugely successful MAG range but add a little more bang for your buck with the addition of an Overdrive control, which can be easily dialed in on the front of the amp and also foot switched in and out using a standard single latching footswitch.

The MAG 300H head features a potent new fan-cooled 307 watts RMS power section. Rotary bass, middle and treble controls are supplemented by smaller rotary controls providing 15dB of cut and boost at 220Hz and 1.6kHz, providing a comprehensive 5 band EQ section. Additionally, front panel push switches for Bright and Deep settings provide instant access to attacking and warm, rounded sounds respectively and, on the subject of low-end response, the trademark Ashdown sub-harmonic generator is ready and able to deliver truck loads of earth moving tone if called upon. Inputs are provided for active and passive instruments and the front panel also features an effects send and return, a tuner/line output and a balanced DI output for direct connection to a mixing console.

With the MAGs now achieving EVO III status, the amplifier also includes a built-in compressor with precision sonic control.

    Comments about Ashdown MAG 300H EVO III Bass Amp Head:

    This head is absolutely astounding to me. I have been playing bass since I was six years old and have owned numerous setups and gear. My old amp went, and since I enjoyed the sound of my Ashdown Overdrive pedal so much, I figured I'd give the head a try since I needed a new one. This thing blew me away. Built in Compressor, Overdrive (Same distortion as the Ashdown Overdrive pedal), And Sub Harmonics. Not to mention an EQ section with endless possibilities. The amount of flexibility in this head is amazing. DON'T let ths 300 watts fool you. This thing is LOUD. It's not like those 6 LB 1000W heads loud, but its a very warm, very rich well-rounded sound, with distortion and compression if desired. I've played venues without PA systems and I received compliments from other musicians. I have it running through an Avatar 4x10 bass cab and I can be clearly heard through three guitarists and a very loud drummer. Don't think twice. Buy it.
