PJ X4 or PJ Double 4?

[Rob MacKillop]

I need a small amp for home use, low volume, headphone option, play solo or with backing tracks, 4-string bass so no need to be concerned about articulation of a low A 5th string. 

 

Both the Nano and the Double 4 are similarly priced, the Double 4 being slightly more expensive.

 

I'm wondering what the difference might be in sound quality. I don't slap, am more focussed on 1950's to 60's-style jazz playing with either a fretted instrument or a fretless. 

 

Your thoughts would be appreciated.
