Anyone use a Clean boost pedal?

I use a TC Spectracomp into a Tech 21 VT Bass to achieve a nice saturated tone without fizzy distortion, but there are some times in the set (eg the bass solo in 'substitute') when I could do with increasing the volume a few db but without changing the tone or adding more distortion. I'm thinking that a TC spark mini after the VT might do the job, but there are a few other pedals that might be suitable like the Electro harmonix LPB-1 nano and various cheap & cheerful mini pedals in the £15

Also, I must add ... with it having a both gain and volume controls, it’s possible to get a very decent overdrive on. Pretty handy having that there at the very tail end of the chain. It gives me post-filter/ modulation dirt options (all my other distortion is in front of the filters/ modulation). I’ve found it to be a surprisingly versatile little piece of kit. It has added breadth to my palette, sure ... and I only set out for a clean boost
