Its feature set is built around a 5-band rotary EQ — covering Bass (100Hz), Lo Mid (220Hz), Middle (660Hz), Hi Mid (1.6kHz), and Treble (7kHz) — each with ±15dB of adjustment, alongside a Deep boost and a one-touch Shape switch for instant classic Ashdown tones. On-board processing includes a one-knob compressor, a footswitchable tube-emulated overdrive, and a footswitchable sub-harmonic generator for added low-end depth. Connectivity covers high- and low-impedance instrument inputs, a line input for backing tracks, balanced DI output, tuner output, effects loop, and two speaker outputs accepting a minimum 4-ohm load. The RM 420 is a discontinued model, making used examples the primary route to ownership.\u003c\/p\u003e\n\n\u003cp\u003eA great opportunity to own a Ashdown RM 420 Head at this price point.\u003c\/p\u003e","brand":"Ashdown","offers":[{"title":"Default Title","offer_id":53951199641937,"sku":null,"price":139.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/6913\/0833\/files\/d6a2ea9a-b142-465b-aa01-cfdd6aff6962.jpg?v=1780568097","url":"https:\/\/www.audiotrader.co.uk\/products\/ashdown-rm-420-head-bass-amplifiers-fair","provider":"Audio Trader","version":"1.0","type":"link"}
