Product details:

The idea behind the OB1 range was to combine a guitar amp and bass amp into one allowing you to add harmonics and layers of overdrive to a core bass tone without having to take more than one amp out on the road. Combining into one amp also enables you to switch from your clean tone to heavy tone at the turn of a knob or stomp of a footswitch (included). Inspired by the OB1 Amp Heads, the OB1-300 Combo houses a 15” Eminence neodymium speaker in a carefully designed front-ported cabinet, and this configuration is the ideal match for the OB1’s fearsome tonal platform. The two elements combine to offer an immediate attack and a seriously punchy low end, dishing out warm contemporary cleans, grinding vintage grit right up to heavily distorted mayhem . Most importantly, the OB1-300 Combo remains focused at all extremes of its wide-ranging tone controls – perfect for the bedroom, the bar or the big stage. The OB1 splits the input instrument signal into two separate paths. One side amplifies the clean signal, with all the clarity you would expect from Orange. The other adds stages of gain to the upper harmonics only, controllable via the amp’s Gain knob. These two elements are combined using the amplifier’s Blend control which adjusts the mix between clean and dirty. The Blend control can then be remotely engaged or defeated using the optional footswitch (included). The Gain and Blend’s range allows for almost anything, from a subtle level boost to cut through the mix, added girth and presence at moderate settings to fatten up chorus passages, to fully saturated savagery at the extremes. However you dial it, the OB1 always maintains the critical low end definition, right the way up to the most offensive settings.
