, none I can think of comes close to producing authentic tube tone like the Bdi21

Who wants to spend thousands of dollars and lug around hundreds of pounds of gear, and replace unreliable tubes every year?

Good clean tube tones with classic ampeg svt mid notch.

Adds some good ampeg/tube like tone to your signal chain.

It is NOT a substitute for a classic tube amp, but with low expectations I was really impressed with the positive sound it gave me

Honestly this was what i wasn't expecting from what i paid, it totally blew my mind immediately after plugin it in and doing some tone settings, it reminded me of a warm tube sound from an SVT head and it responded crisp and smooth , whether you`re playing by pick or

The BDI21 gives me a nice warm adjustable tube sound for very little cash output.

The amp emulation capabilities are subtle, but you can get just enough tube compression to take the edge off and get a fairly tight, smooth, and controlled sound (with just enough growl when needed).
