The Ashdown Rootmaster EVO 500W 1 x 12 Bass Amplifier Combo is a powerful combo that is packed with a range of features that raises the bar for professional-level bass amps. Whether you're an amateur or a pro, you're going to want one of the beauties at your disposal either on stage or in the studio.
Raw Ashdown power
The Rootmaster EVO 500W may be delightfully compact in form, but it boasts a marvellous output that can hold its own in the most demanding playing environments. Equipped with Ashdown's Rootmaster EVO series' preamp, there are passive and active input jack sockets to choose from, accommodating bass guitars equipped with active or passive pickups. Ashdown's White Line speaker guarantees that no matter what, the output retains a smooth character. Plus, there is an additional 8-Ohm extension cabinet output, should you need any more power in your arsenal.
Intuitive front panel control layout
Across the front panel, you have a selection of controls that allow you to shape your tone with ease. The top row carries the impressive 5-band EQ section. Intricate signal manipulation is simplified thanks to the excellently calibrated controls. No matter where you're performing, what bass you're playing or playing with, you can use the EQ section to ensure your tone shines through clearly.
The all-new compressor design allows you to attenuate the signal from a tight and clipped response - emphasising each and every note with precision - to a huge, rounded sound with lots of bounce and width. If you're looking to inject a little tube-emulated overdrive into the signal, the Drive control allows you to dial the amount to your heart's content, ranging from subtle sizzle to harsh crackle. Whatever style of music you play you can find a level of overdrive to suit you.
The Sub harmonics section produces sub harmonics an octave below played notes, which can be mixed with the level control of the amp for your perfect blend. The benefit of this is to thicken up your sound and create a fuller-sounding output.
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 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.
