Unless you simply have to have the TweeterTone and the extra headroom, there’s not quite enough to encourage existing RH450 users to upgrade, but we suspect that this update of the popular model is aimed more at those bassists who haven’t yet taken the plunge, or have been holding out for a more powerful model. At £849 RRP the RH750 is not signifi cantly more expensive than the RH450, and although this is clearly a high-end piece of equipment, we believe it is priced sensibly.
