Some thoughts on SLB300
First
Why bother ? Still the case a standard BD of reasonable quality produces THE tone we all aspire to BUT always subject to;
1. Players competence
2. Sting type ( as we all know, a minefield of expense, frustration, and, occasionally, satisfaction ! )
3. Where you are playing (natural acoustic of playing space make so much difference)
4. What you are playing ( for me pizz. 99% of the time)
5. Who you are paying with
So my comments are broadly based on my playing situation which is usually;
1. Competence - keen amateur, coming from electric bass guitar - fretless electric - double bass ( westone thunder / westone thunder 1A / fender early 70's jazz / squier bespoke fretless, bespoke Zoot fretless / Aria travel fretless / hatpeg Czech Republic(1918 to 1938) carved bass, SLB300 )
2. Using SLB300 with supplied strings ( D'Addario Helicore Hybrid Light) which are not too different to the Evah Perpetuals I have ended up with on the DB. I have not tried different strings on the SLB yet as I like the supplied strings tone and feel.
3. Practice - large front room, SLB provides enough acoustic volume and tone to use without amp if solo practice. Playing to other music needs amp.
4. Most paid work is in small semi -pro swing band ranging from small festivals, pubs, small and medium sized halls, private functions (indoors and outside) - so never the same except repeat gigs and re-producing the lovely low volume tone the SLB gives at practice is still a struggle the same as for acoustic DB - BUT crucially less of an issue because we can now get Volume without feedback. The bass does not go through the pa for most of our small gigs but obviously does on festival gigs. ( thesultans.org - judge for yourself, don't be mean!)
5. The swing band is two saxes, guitar, singer, drums and moi. - drummer is of the quieter jazz variety but I struggled to get a consistent, tone full front of house sound with the hatpeg - into Ear Trumpet Nadine mic - into Acoustic image with enough volume. Secondary issue is transporting the DB or leaving it unattended anywhere - haven't come to grief yet but come very close many times.
How does SLB cope ?
For practice, no issues, feels like the acoustic version, plays like the acoustic version, and sounds like a (very quiet)acoustic. I chopped a little off the bridge feet to allow some height adjustment and the action is currently a little lower than my DB but the board will need some Martin Penning ( Frome based - DB luthier ) magic attention if I wanted to go really low (which I don't). I have gone a little lower for playing comfort over longer gigs. I suspect Martin would also thin out the supplied bridge as it is a little chunky - there is some comment on forums on this.
For live playing I usually use have "tone" maxed out in favour of one of the supplied tone shapes ( if you don't want these tone maps why buy the SLB300 in the first place ) as opposed to the undoctored piezo tone. I like the ability to boost the volume from the instrument rather than having to access the amp in the middle of a tune or between tunes. I usually have the bass and treble on middle and just use the volume control if a tune needs more upfront bass.
There is a noticeable difference between the supplied 3 basic tones but I think the differences get lost as the overall band volume increases. On a number like "Fever" the richer tone is welcome and can be heard given the sparse arrangement, most of the time I leave it on the second option ( quality dynamic mic ? ) which fits best with the wide variety of stuff we do. As the amp volume goes up I usually end up reducing the lower frequencies on the amp to restrict boom, but the SLB bass and treble contols stay close to middle.
In a difficult venue with difficult acoustics ( super low ceiling - boomy - etc ) I content myself by having enough volume headroom even if I need to loose a lot of bottom end to get some clarity of note tone so the SLB is easier to use than the hatpeg. The band have started to hear me better due to all this - I usually use a an upshot extension speaker on the opposite side of the stage so all the band can enjoy the bass notes !
Transport and storage obviously less stress. Has accommodated assembly and dis-assembly without issues so far. About 3 minutes to assemble from case if you take your time.
SLB battery life - my advice, ALWAYS carry spares, the battery (like all batteries) chooses to start failing mid gig, a red light starts to flash and panic sets in - how many minutes left, will I make it to the end of this set ?. Acquaint yourself with exactly how the replacements must be fitted in the pop out holder, a dark stage, mid gig is not conducive to this . The output starts to fade as the power diminishes and you are unlikely to get by on the unpowered piezo.
The SLB produces more sustain than the hatpeg but I damp this automatically the same as for fretless bass guitar. Not sustain to the extent of a fretless guitar but it is definitely there.
I purchased the top bout extension ( ouch ) which gives a better playing position to match the hatpeg. SLB seems to stay in tune with itself consistently.
Recording - nothing done in a studio with this but I have put the SLB straight into a Yamaha digital recorder ( AWB 16 ) and the result is quite acceptable. On a Festival Stage, make sure the stage engineer gives you full fat foldback sound ( then reduce bass to taste) - if they treat the SLB as an electric guitar they will suck all the bass life out of it - a very nasty onstage experience if you are giving it your all on the first number and all you can hear is ultra tinny. One has to hope the front of house is not the same.
Is it worth it ? I think so, the re-sale value is good and as long as I look after it properly its net cost to me will be acceptable and the ability to be heard clearly and with DB tone on our gigs gives me playing satisfaction and suits the stuff we are doing.
