FOREWORD
Congratulations on the purchase of your new Eden World Tour Bass Guitar
Power Amplifier. All of us at Eden are totally committed to providing you
with the very best bass guitar systems in their class. Our goals are to offer
you the outstanding performance quality of a top-notch, professional bass
amplification system at a reasonable price point, and to make World Tour
amplifiers the most musical and reliable Bass amplifiers available.
This manual will cover domestic and international versions of the WT1250
and WT1550 amplifiers.
You have purchased what we feel is one of the finest bass power amplifiers
in the world. The new Tone Control section, featuring individual controls for
each channel, allows the user to quickly adjust to difficult rooms. The AGC
Limiter and Thermal Safety System protect your amplifier from potential
damage. The compact, rack mountable package houses modular circuits
made with superior components and designed for years of trouble-free
service.
The Eden World Tour products group is the result of our quest for ultimate
bass tone and maximum reliability. Your new Power Amplifier features our
latest input section, using dual pre-amp tubes to provide unequaled warmth
and tonal adjustment to accommodate varying room acoustics. We believe
the result is more than worth the effort and think you’ll agree.
Your amplifier was designed, engineered and manufactured equivalent to
aircraft vibration standards and housed in a one-piece steel case with steel
top to ensure maximum reliability. The modular design allows quick repair
in the field should such a need arise.

The Eden line of World Tour amplifiers is the result of our research and
development in combining high performance and compact size. Just as a
skilled craftsman needs good quality tools that won't let him down on the
job, so does a good musician. We hope you enjoy the tool we’ve created for
you. Have fun; play low!
Please read this manual in its entirety before operating your new amplifier.
Failure to do so could result in misuse or damage. We’ve taken the time to
write it, which was a lot longer than the time it will take for you to read it.
Help us help you by taking a few moments to learn how to properly use your
new amp. You’ll be glad you did!
CAUTION!
Your ears are your most important piece of equipment.
Unfortunately, they cannot be replaced as easily as your
other gear. Please take the following warning seriously.
This product, when used in combination with
loudspeakers and/or additional amplification may be
capable of producing sound levels that could cause
permanent hearing loss. DO NOT operate at high volume
levels or at a level that is uncomfortable. If you
experience any discomfort or ringing in the ears or
suspect hearing loss, you should consult an audiologist.
Thank you for your purchase of an Eden bass guitar
product. This unit has been designed and constructed to
give you years of trouble-free service.
Please take the time to review this manual
and to send in your warranty registration card.
