At my age it’s very important to have amplification gear that doesn’t break my back. The Ashdown RM 500evo is light in weight and heavy in tone. It pretty much reproduces the sound of your bass and you can add some eq and effects. It takes a while to learn how the eq works best. There is a shape button which gives a bass heavy. Mid scooped tone. Start there. Depending on your bass you may want to pull back some bass and compensate for the mid scoop. You also have a compressor which as well as rounding off those peaks will add volume to your sound. In addition there is a drive control...a kind of tube simulator. I find just a little gives a warm tubey tone. Then there is the sub harmonic control which adds an octave down. Used subtly it adds a hint of extra bottom.
