Barcza,
Just so you know I use Walter Woods Amplifiers and find them to have just the right combination of pre amp voicing, power, and size. Something that I've noticed is that amps that have a pre amp voicing that sounds great with Double Bass don't often sound as good with Electric Bass. For lack of a better term I would consider Double Bass e.q. to be more concerned with controlling certain frequency ranges. It's tone controls are focused more on having a "natural sound".
Conversely many of the amps that sound great with Electric Bass
have pre amps to emphasize tone qualities and boost them. This something that may not be desirable for the Double Bass. Since this is the case IMHO the all the amps on the market favor one of the two instruments.
IMHO this puts the amplifier manufactures in a paradox, Unless they built a two channel amp with different pre amp voicings. Even the Walter Woods Electro Acoustic amps don't to that. Walter addressed the problem buy inserting a "Balance" control between the Treble and Bass to shift the emphasis between the highs and lows and a "Vari control to shift the midrange emphasis between low mids and hi mids.
Epifani also addressed this issue with totally different controls on the two pre amp channels. Since this is the case IMHO the all the amps on the market favor one of the two instruments.
Loud and Clear with the Double Bass is also a particularly tough nut to crack. IMHO the louder you play with a stage amplifier the more trouble you will have. It's easier for me to go though the house system with a good mic and use a conservative sized amp on stage, than try push sound from the stage in larger concert venues. Just my opinion though.

I don't agree that all amps on the market favor one of the two. Within these threads, I have railed against "voiced" pre-amps on a number of occasions. I just don't like that practice and never will. For those who are not familiar with pre-amp voicing, it refers to "building in" a tailored frequency response rather than designing the pre-amp to have a flat response. The Baggs pre-amps, for example, incorporate voicing, others, like
fdeck's little gem, do not.
With regard to tone-shaping controls, I agree that some amps are built with controls that are better suited to double-bass or bass guitar. Those amps then, are, indeed, better suited to one or the other. In fact, I would say that
most amps would favor one of the two instruments.
I have also remarked in the past how powerful and flexible a tool is the parametric tone-shaping section of the EA iamps. This discussion points to yet another reason that parametric tone-shaping is desirable. Given the ability to vary center-frequency, bandwidth, and relative boost/cut of a number of well-placed bands, such an amplifier need not and does not favor one or the other instrument. Thus, I think the EA amps (and any other amp with such flexible tone-shaping circuitry) are the exception to the rule. So, too, would be amps that have
no tone-shaping circuitry. Of course, most of us would not want such an amp.
