I have been offered a very good deal on a PJB C8, 4 ohm, 800 watt. I play in a pub rock n roll band - the usual hits - guitar driven. We are a 3 piece and not the loudest... Any users/reviews? Will it shove enough air? my thought is that it is an easy rig to transport and live with and i can easily add another C8 monster rig.... I use an ampeg scr-di preamp and crown xls 800 watt power amp. **regret selling my SWR Golight 112’s..

@Matt P TBH, I will probably flog the Boogie TL. I prefer to try and work the issue a bit and h cab I got was not bank breaking. I think that the SFE-200, tune the cab to 66Hz with 2 x ~7cm ports looks pretty good (Thick green line). £107 for the drivers and a couple of quid for port tubes. Looks like it will even be an upgrade sealed to (Red Line). The thin green and thin blue are the TF0818's - which I can sell on.

In other news, I have a boogie TL806 cab with an evm12L loaded in it. Useless for bass, but if I block a port it should lower the cab rsonance down to ~50hz. I then need a good 12” bass driver that works in that cab! Any thoughts?

Good point, but i can re-speaker this cab for £100...and the size/weight is fine...

Thanks Bill - May I take the opportunity to thank you for your help, not often I get to interact with an industry legend. Messing with the model tonight shows that porting the box with the original drivers seems to be the best option; Thick green line; The SFE-200 seems to go bonkers vented (thin green line), but be far better sealed

Thanks @Bill Fitzmaurice - I am not sure I am in the zone to spend on the B&C, but considering the SFE-200 are £26 each, I can sort the entire cab for ~£100. I think it is a case of figuring out venting for best performance and living with it. I.e. improvement for minimum investment! IN WinISD, how do I model the port?

Wondering if i can tune the port better....

@Twincam Yes, red line. I amguessing it just indicates extended range from the lower blie line - tf0818 drivers

Thanks Bill, so my current cab volume is 84 litres, therefore i have 21 litres per driver - assume the above is with those specs and a 10cm port?

Porting would be a 10cm hole with an 8cm tube....

So, I modelled it; Have no idea what I am doing! I made the volume 84 litres of the box. Thin Green is ported to 10cm with the SFE-200 driver - VAS 13.6 l Thick Green is ported to 10cm with the TF0818 - VAS 9.4 l Red is sealed with the SFE-200 driver VAS 13.6 l Blue is sealed with the Eminence Alpha VAS 17.1 l Lower Blue is the TF0818 driver sealed - as is now. The box resonance drops to 40Hz ported.

@Matt P Do you have a link to the WinISD download? I think this is an early cab - TF0818 drivers, no porting - offset drivers and a horn switch (high/off/low). Rubber 'fender' handle on the top.

Any thoughts on this as a bass driver; https://www.lean-business.co.uk/eshop/faital-pro-8fe200-8ohm-8-150watt-speaker-p-2276:8d6ac59af11625534a44172ce1f6c7a9.html?zenid=ia3g2j1j418tlso6sdg387b8j4

Hi All, So, I bought an Ashdown 408 4x 8 mini. It billed as being loaded with Sica neo drivers, but on inspection is loaded with Celestion tf0818's, I am not too bothere tbh. However, I am getting very little definition of my low E and if I drop to D it gets a bit flappy. I am no expert, but I have 2 lines of thought; 1, Driver frequency handling - the Thiele small parameters set the TF0818 as more of a mid driver with low excursion (XMAX) and frequencey range from 70Hz. I.e. the driver is not handling the bass well. 2, Lack of porting the cabinet - it is completely sealed - i.e. the cab is not allowing the drivers to handle the bass I am happy with the cab size, weight and the mids are great, but the bass is a big flabby. I have an option on some SWR Celestion BG8-60 drivers or Faitalpro 8fe200 - The faital looks to be more of a bass driver. Or I can drill a bloody great hole in the front of the cab and port it with a tube. Thoughts and advice please.

I can confirm, it all works! Panama Conqueror into channel 1 Crown 300w PA into Boogie Thiele cabinet - Still get the full tube sound, just massively louder! Ampeg SCR-DI into Channel 2 Crown 300w PA into Ashdown 408 cabinet (Courtesy of Sharkfinger) - It is bloody loud and absolutely stonking! I can definitely recommend the Ampeg SCR-DI, it is beautifully built and super rugged. The sound is almost bang on to a vintage ampeg and is super flexible on tone. The Scrambler is a 'nice' addition and gives more bite, but it can get undefined and a bit fuzzy. I have the blend set more towards clean bass and only a slight amount of distortion, almost replicates a preamp tube being pushed on the heavier/louder notes. The Di works well and the phones socket is a definite bonus, I can sit with my headphones on and bother no one! Hoping my wife now buys me something else for Christmas as I already have my pressie!

So, it turns out that my better half bought me an Ampeg SCR-DI for Christmas, I won't go in to detail, but I kinda blew my own surprise..... So, the dual rig will be; Panama Conqueror into channel 1 Crown 300w PA into Boogie Thiele cabinet Ampeg SCR-DI into Channel 2 Crown 300w PA into Ampeg 2 x 10 Classic Series cabinet In terms of weight - the heaviest bit is the borrowed Ampeg Classic Series cab @ 27 kg....but seeing as I am carrying both guitar and bass, I am not so bothered. I guess that the nice thing is that I can play bass on headphones at home.....!

Okay, so i tried some modelling gear on friday and i admit, whilst being a tube junkie, it was very good. But i am loathed to shell out and re rig just now. For cheapness while the band are still building our set; my current guitar rig (5f2 clone head +evm12l loaded boogie) with load box into a crown power amp for live usage. An ampeg pedal/di into crown second channel for bass into a borrowed ampeg cab or i could sell the guitar rig and buy an ampeg svp and just run the ampeg through a power amp into the ampeg cab...use for both bass and guitar i am still a bit old school on tube preamps and simple pedals...

Wow, wasn't really aware of FRFR, I was always an old school guy 'No tubes=stinky poo sound'. Maybe I need to get out more and try stuff!

Hi All, I was on Basschat ~5 years ago, but dropped off for a bit and dropped out of music for a period - kids, work blah! Anyway, I am back and need some advice. So, I am a converted to bass guitar player, but in my new band I share bass and guitar duties. As such, I don't want to be carrying 2 rigs. The other guitar/bass guy has his own gear, which we can share on smaller gigs. But on larger gigs, I would like my own stuff. Here is the conundrum: When I stopped playing live I sold my lovely Markbass and SWR kit and my basses. I kept hold of my 5watt Panama Conqueror head and a Mes Boogie Thiele cab with EVM12L for 'bedroom guitar' and have recently procured an OLP stingray copy which was fitted with a basslines pickup and a badass bridge! I don't want to buy another louder guitar amp head and a complete bass rig, so this is what I am thinking. **I am a big fan of the ampeg/Stingray sound! Output my 5w Panama tube head via a load box into a Stereo power amp, using 1 side of the power amp to drive the boogie cabinet - This should give me whatever wattage the power amp is into the Boogie. Buy an Ampeg SVT classic pedal or Ampeg DI, output that to the second channel of the power amp and drive a purchased lightweight cabinet - This should give me effectively an ampeg pre amp and load of power to drive the cab and the option to DI I am hoping there will be no crossover within the power amp or any impedence mismatch that I have missed, but it essentially means I only carry; 1 Bass Guitar 1 Guitar 1 guitar amp (or even just my pedal board) 1 Bass pedal 1 power amp 2 small lightweight cabinets Did I miss anything? Or is it easier to just buy a second rig?
