Bass amp

Hi
Is there a kit that i could make a bass amp for practice purposes ? I was thinking stereo bass amp with more then 15w per channel, with stereo preamp (volume, balance, bass, treble and maybe middle).One channel for pick up, one for piezo.
Can u recommend power amp, pre amp and power supply !
I have a D.I. box(Behringer MIC200), and i think that would help with impedance.

Thanks

No need for stereo.
You can use K8060 as power amp.
Sorry, no dedicated preamp for bass guitar.
If guitar features line out, then you can use K8084 preamp.

That is a thing, there is a need for stereo, if i didn’t want it, i would just go to a pawn shop and got a used small amp! So, again, what do u think what is the best STEREO kit to run instruments, and can any of them do that job? And do u have an amp(stereo) that can be bridged, because my bass can be stereo or mono, depends on a cable i insert(Fishman POWERCHIP)
Thanks

If you insist on stereo, you will require two K8060.
They cannot be bridged.

What about K4004B ? Will it do the job? That’s a stereo/ bridgeable, and I could choose input sensitivity.
Thanks

Yes, but K8060 is better.

In what way? Quality wise ? Better parts, better sound?
