P18C Park '18' Combo (1974/Tremolo)

18-Watt Park, (Switchable 18W, 7W, 1W, 0.5W), Cascading Gain

Based on the Marshal 18 (1974 Model Series) and WEM Dominator.

Ambitiously building on a twice world famous circuit, the Park P18 Combo is up for the challenge with Mitch Colby’s additional upgrades - the ability to switch into ‘High Gain Mode’ by cascading the channels, and to now switch from 18 watts down to 7 watts, 1 watt or 0.5 watt, while still producing ‘record quality’ tone.

Mitch: ‘a great little stand alone tube amp with the ability to play at extremely low volumes while retaining great tone (most low volume amps 'whimper' but not the Park 18 in 0.5watt mode)’

This remarkable amp/circuit started out as the WEM Dominator, a great EL84 amplifier, that really shines with its ’throaty overdriven sound and smooth tremolo circuit’. Jim Marshall’s ‘18 Watter’ which has also become legendary was based on the WEM Dominator but he brought it to a new level of aggressive Rock sound - ‘It’s got the grind of a much bigger amp’.

With his added features Mitch has taken this circuit to a new even higher level of ‘beautiful clean sounds and aggressive rock tones’ with the ability to produce them at Reduced wattage.

Mitch Colby recommends pairing the Park P18 with a ‘reconed’ alnico Blue ‘Vintone’ 12” Speaker - it is ‘brighter, punchier, more efficient ( louder) bolder and works great with the clean and Overdriven sounds of the Park P18.

For the Original Vintage sound pair with a Celestion 12” Greenback - warm but clear clean sounds - smooth but rocking overdrive.

The Park 18 Head has all the carefully crafted tone and feel of the P18 Combo in a compact Head format.
