    Advice Please

    Thanks for the ideas. In searching around I came across the G&L L2000. How does that stack up in terms of tone (compared to my MM)? The p'ups look the part, don't know if they sound the part...

    Advice Please

    Thanks. Unfortunately no place around here sells Music Man or G&L. How do the Big Al and Bongo compare to the Sterling 5, sound-wise? I picked up a StingRay 5 and it almost broke my neck. Let me put it this way, my favorite guitar is a Parker Dragonfly. Even my Strat seems heavy by comparison...

    Advice Please

    I'm looking for a little input regarding a new bass. There aren't a lot of stores in my area where I can try out instruments so I'm hoping to get a little feedback here. I have a Fender American Standard J w/ DiMarzio p'ups. I love the feel of the instrument but I was never crazy about the...

    VOX Amplugs

    I saw these on the 'net the other day but don't know how they sound with bass. I'd like to hear from anyone who has used one. Also, is the headphone jack normal 1/4" or mini 1/8" style? Thanks

    Is there a limit to the number of drivers a given amp can power at a given impedance?

    Ya know, it's interesting to take a step back and look sometimes. When I first thought about this (putting two speakers in series), I did what I usually do when a student asks a question; namely, I looked at the general case (because that's usually what they want). Putting two arbitrary...

    Roland Micro Cube Bass RX Cube Amp

    "No chance"? Nah, I guess that depends on your definition of "quite loud". If you mean 100 dB-SPL in your room's reverberant field, then no, it's not going to be loud enough. My experience is that it is plenty loud if you're practicing at conversational level. I must admit, the one feature I...

    Is there a limit to the number of drivers a given amp can power at a given impedance?

    That analysis is fairly obvious and I will note that it doesn't mention the output impedance of the driving amplifier (i.e., analyzing the Q of the loudspeaker by itself versus the amp/loudspeaker system- that is, assuming that you have a perfect amplifier). Being the sort of curious fellow...

    Is there a limit to the number of drivers a given amp can power at a given impedance?

    Just what do you think the electrical equivalent circuit of a dynamic loudspeaker is?

    I made my own speaker boxes, what do you think?

    "limited capabilities of the Delta 15"? I admit that I'm not familiar with that particular driver, but I assumed (apparently incorrectly) that it had fairly good excursion abilities given the application. For that matter, what's the fs of the 10"? Is it particularly high? As far as parts...

    Is there a limit to the number of drivers a given amp can power at a given impedance?

    I assume that you've never heard of Thevenin's Theorem or took an AC circuit analysis course. I do this stuff all the time. I've been teaching it for over 20 years. The theory is all well established. Trust me on this: If you put something in series with a resonant circuit (which is what a...

    Is there a limit to the number of drivers a given amp can power at a given impedance?

    Ouch. I don't want to sound like an *ss, but some of the terminology in here is making my head spin. Maybe I'm a little sensitive to this as an electrical engineering college professor, but bear with me a moment. First, I haven't fully figured out WHY the OP wants to do this. What's the point...

    Speaker Cab design software... heLp?!?

    No need to Google it, I posted the appropriate formula, above ;-) As an electrical engineer I completely agree with the "balance/compromise/choice" comment. I'm always explaining to people that there is no such thing as a universal "best". What's best depends on the system requirements. I...

    Speaker Cab design software... heLp?!?

    Excessive use of damping material (fiberglass batting et al) can reduce the effectiveness of a vented system. It has more of an effect than simply "stop(ping) mid frequencies bouncing around inside the cab". It can effect the damping of the system (i.e., the Q of the resonant system) and thus...

    Speaker Cab design software... heLp?!?

    An optimal box is just that, optimal. What it gives you is the most extended monotonic response (i.e., no ripples or peaks in the bass response). In no way does this mean that you can't use a smaller box. If you do, you will most likely give up some deep bass and you'll probably get a resonant...

    Fender Jazz 24....none more BLACK....

    I've never played a Jazz 24. I'd don't want to sound dumb, but do you mean "balance better than a regular Jazz" or "balance better than if they didn't do that"? Overall, does it feel much different from a "normal" Jazz? I like something that just perfectly balances on my right thigh when I'm...
