The Ashdown Rootmaster EVO 500W 1 x 15 Bass Amplifier Combo is a superb combo for those who need a reliable workhorse for practising, gigging and touring with. Equipped with Ashdown's White Line 15-inch speaker, the impressive RM-500 amplifier is given the perfect partner to project tones with exceptional clarity.
Impressive Ashdown power
The Rootmaster EVO 500W 1 x 15 boasts a compact form that belies its powerful capabilities. The RM-500 amplifier delivers a smooth sonic output, with a selection of inputs and a wide range of tone shaping options to play with. The active and passive instrument inputs allow you to connect either active or passive pickup-powered basses. The White Line Speaker ensures that tones are delivered with the utmost clarity. The additional 8-Ohm extension cabinet output allows you to increase your playing power when desired.
Intuitive front panel control layout
Across the front panel, you'll find a range of control that enable you to readily sculpt your tone. The top row carries the impressive 5-band EQ section, which features Bass, 240Hz, Middle, 1.5kHz, and Treble frequency shaping. Wherever you're performing, you can adjust the amp's output to suit any playing environment.
The design of the compressor means that you can attenuate the signal from a tight response that focuses on note attack and note clarity to a swelling, almost dirty tone with plenty of depth. Whether you want a tight clean or a chunky overdriven tone, the built in Drive control allows you to ramp up the drive to suit your needs. The Sub harmonics section produces sub harmonics an octave below played notes, which can be blended with the level control to create the right mix for you. The bonus here is a dense, thickly-packed tone that fills out your sound.
Across the front panel you'll find the Active and Passive instrument inputs. Across the rear panel there are a range of connectivity options for you to play take advantage of, including: Speakon connections, DI Out, FX Loop (Send/Return), FS-2 Out, and Line In.
The FX Loop Send and Return connections allow you to set up external effects pedals free from the pre- and post-amp stages to give you greater control. The D.I. XLR output delivers a balanced signal, perfect if you want to send a feed straight into a mixing desk for recording or monitor mix during a gig. Not only that but a unique Speakon speaker output jack allows you to connect into a live PA desk where an XLR jack isn't available so that all bases are covered. The FS-2 output allows you to manipulate the Drive and Sub Harmonic effects via an external footswitch.
Durable cabinet design
As we've come to expect from the team at Ashdown, the Rootmaster EVO 500W 1 x 15-Watt is built to withstand all the abuse that comes with life on the road. The cabinet is built using lightweight ply to reduce weight, without compromising on that signature Ashdown sound - sparing your back when loading in and out of venues, whilst preserving your mighty tone. Encased in Buffalo tolex and employing a black grille cloth, the cabinet achieves a cool yet understated finish. Carrying handles on either side of the cab make it nice and easy to transport.
